Key Mapping

To customize key mappings, you need to configure input_mapping yaml entry

Defining input_mapping replaces the built-in bindings — it does not add to them

As soon as an input_mapping section is present in your contour.yml, Contour's built-in defaults (Ctrl+Shift+V, the Ctrl+Shift+P command palette, the tab shortcuts, …) are discarded, and only the entries you list are active. Writing an input_mapping section is a declaration that you are defining the full set of bindings.

The contour.yml that Contour generates on first run already contains every default binding written out in full, so editing that section keeps the defaults you did not touch. If you are writing a configuration by hand and want to keep the defaults, start from a generated one (contour generate config) and add your entries to the existing list.

Built-in bindings

A small number of bindings are built in and do not appear in input_mapping:

Binding	Action
Ctrl+Tab / Ctrl+PageDown	Switch to the tab on the right (wrapping around)
Ctrl+Shift+Tab / Ctrl+PageUp	Switch to the tab on the left (wrapping around)
Ctrl+Shift+G (Linux, Windows) / Cmd+Shift+O (macOS)	Open the last command's output in the pager named by command_blocks.pager (needs a shell that marks its commands with OSC 133). With nothing to open the chord is swallowed rather than sent to the shell as ^G; on the alternate screen it goes to the application
Ctrl+Shift+L (Linux, Windows) / Cmd+K (macOS)	Clear the scrollback and the screen above the current prompt (ClearToPrompt). On the primary screen only; with nothing to clear the chord is swallowed rather than typed
Alt+Shift+Arrow (Linux, Windows) / Cmd+Option+Arrow (macOS)	Move the focus to the pane on that side. Some desktops and keyboard-layout switchers grab Alt+Shift; if the chord never reaches Contour, bind another one to FocusPaneLeft/Right/Up/Down in input_mapping
Ctrl+Shift+E / Ctrl+Shift+O (Linux, Windows)	Split the active pane side by side / stacked
Cmd+D / Cmd+Shift+D (macOS)	Split the active pane side by side / stacked
Cmd+Shift+Enter (macOS)	Zoom the active pane to fill the tab, and back
Ctrl+Shift+K (Linux, Windows) / Cmd+Shift+K (macOS)	NewWindowTo: open the Connect picker to choose where a new window's sessions live
Right mouse button	Open the terminal's context menu
Ctrl + triple-click with the Left mouse button	Select the output of the command under the pointer (needs a shell that marks its commands with OSC 133; on the alternate screen, which has no commands, the click selects as usual)
Horizontal wheel / two-finger sideways swipe	Switch tabs

The default chords added since your configuration was generated (see Default chords) reach it the same way, among them Ctrl+Shift+C, Ctrl+Shift+W, the pane chords and the macOS ⌘P, ⌘W and ⌃⌘ chords.

These are consulted only when your input_mapping does not claim the same key or button (for the triple-click, the same button and click count), so binding one of them yourself replaces it.

They are built in rather than listed as defaults for the reason given in the warning above: an input_mapping section replaces the built-in list wholesale, and the generated contour.yml writes every default into that section. A binding added to Contour after your configuration file was written would therefore be shadowed by your own file forever. Consulting these after yours is what lets a new binding still reach you, while anything you bind explicitly keeps winning.

Ctrl+Tab is taken from the application

Like Windows Terminal, GNOME Terminal and Konsole, Contour claims Ctrl+Tab for tab switching, so a terminal application that wants it (via the Kitty keyboard protocol) will not receive it. Bind it in your own input_mapping to give it back to the application.

Default chords

Every command with a default chord has one on Linux and Windows and on macOS. On macOS the application's chords are Command chords: a Ctrl+Shift+letter default answers to ⌘letter there (Primary, see below). Where macOS already gives the plain ⌘ chord another meaning, the Mac chord adds Shift or moves, and the table says why.

Command	Linux / Windows	macOS	Note
Command palette (OpenCommandPalette)	Ctrl+Shift+P	⌘P, ⇧⌘P	⇧⌘P for VS Code, Zed and Ghostty habits
Copy (CopySelection)	Ctrl+Shift+C; Ctrl+C while selecting	⌘C
Paste (PasteClipboard)	Ctrl+Shift+V	⌘V
Paste without control characters	Ctrl+Alt+V	⌃⌘V	Option composes characters on a Mac, so the Ctrl+Alt chords become ⌃⌘
New window (NewTerminal)	Ctrl+Shift+N	⌘N
New window to… (NewWindowTo)	Ctrl+Shift+K	⇧⌘K	⌘K clears to the prompt
New tab (CreateNewTab)	Ctrl+Shift+T	⌘T
Close pane (ClosePane)	Ctrl+Shift+W, Ctrl+Shift+X	⌘W	Closes the tab with its last pane
Close tab (CloseTab)	—	⇧⌘W	On Linux and Windows, Ctrl+Shift already holds Shift
Select tab 1…9 (SwitchToTab)	Alt+1 … Alt+9, Alt+0 for the tenth	⌘1 … ⌘9	⌘0 resets the font size
Previous / next tab	Ctrl+PageUp / Ctrl+PageDown, Ctrl+Shift+Tab / Ctrl+Tab, Shift+← / Shift+→	the same, and ⇧⌘[ / ⇧⌘]
Move tab left / right	Ctrl+Shift+PageUp / PageDown	⌘PageUp / ⌘PageDown
Split side by side / stacked	Ctrl+Shift+E / Ctrl+Shift+O	⌘D / ⇧⌘D	iTerm2's chords
Focus the pane on that side	Alt+Shift+Arrow	⌥⌘Arrow
Swap with the pane on that side	Ctrl+Alt+Arrow	⌃⌥Arrow
Resize the pane	Ctrl+Shift+Alt+Arrow	⌃⇧⌥Arrow
Zoom the pane (TogglePaneZoom)	Ctrl+Shift+Z	⇧⌘↩	iTerm2's chord
Toggle split orientation	Ctrl+Shift+\	⌃⇧\
Find (SearchReverse)	Ctrl+Shift+F	⌘F
Next / previous match	F3 / Shift+F3	⌘G / ⇧⌘G, and F3 / Shift+F3
Find the selection (SearchSelection)	—	⌘E	A macOS convention; Ctrl+Shift+E splits
Clear search highlight	Ctrl+Shift+H	⇧⌘H	⌘H hides the application
Previous / next command (FocusPreviousCommand)	Ctrl+↑ / Ctrl+↓	⌘↑ / ⌘↓	At the prompt only, as in VS Code's terminal
Select previous / next command's output	Ctrl+Shift+↑ / Ctrl+Shift+↓	⇧⌘↑ / ⇧⌘↓	At the prompt only
Previous / next prompt (ScrollMarkUp)	Ctrl+Alt+K / Ctrl+Alt+J	⌃⇧↑ / ⌃⇧↓	At the prompt only
Open the last command's output	Ctrl+Shift+G	⇧⌘O	⌘G finds the next match
Clear to the prompt (ClearToPrompt)	Ctrl+Shift+L	⌘K	The shell's Ctrl+L, plus Shift
Open URLs by hint (HintMode)	Ctrl+Shift+U	⌘U
Font size larger / smaller / reset	Ctrl+Shift+= / Ctrl+Shift+- / Ctrl+0	⌘+ / ⌘- / ⌘0
Toggle the status line	Ctrl+Alt+.	⌃⌘.
Open the file manager	Ctrl+Alt+O	⌃⌘O

Toggle input method handling	Ctrl+Alt+,	⌃⌘,
Settings (OpenConfiguration)	Ctrl+Shift+,	⌘, (menu bar), ⌃⇧,
Vi normal mode	Ctrl+Shift+Space	⌃⇧Space
Full screen	Alt+Enter	⌥↩
Speak the selection	Ctrl+Shift+S	—	macOS has its own Speak Selection (⌥Esc)
Quit	Ctrl+Shift+Q	⌘Q (menu bar)

A test (ChordParity_test.cpp) keeps the two columns complete: a command bound on one platform only fails the build unless it is listed there with its reason.

macOS defaults

• The menu bar provides ⌘Q (Quit) and ⌘, (Settings…), and ⌘H, ⌥⌘H and ⌘M; Contour binds none of them by default, so they never reach input_mapping. Ctrl+Shift+letter reaches the program in the terminal, and a ⌘ chord nothing is bound to is consumed rather than typed as its letter.
• ⌘K clears to the prompt (ClearToPrompt) on the primary screen; in the alternate screen it is consumed, so a running vim or tmux is never reset. ClearHistoryAndReset has no macOS default.
• Font size is on ⌘0, ⌘- and ⌘+ only; Ctrl+0 reaches the program.
• ⌘X and ⌘S are deliberately unbound (a terminal cannot cut, and there is nothing to save).
• The defaults that hang on Ctrl+Alt plus a character answer to ⌃⌘ on macOS instead, because Option composes characters there (see below).
• ⌥← / ⌥→ move by word (ESC b / ESC f) outside the alternate screen, and ⌘← / ⌘→ / ⌘⌫ edit the line, so these shell conventions work out of the box. Inside the alternate screen ⌥← reaches the program as the Alt+Left it is (CSI 1;3D).

Option as Alt

Option has two jobs on a Mac: composing characters (⌥E then E gives é) and acting as Alt. The profile setting option_as_alt chooses which Option keys are Alt: off, left, right or both (true and false are still read as both and off). One rule applies everywhere:

• An Option key that option_as_alt names is Alt, for every key: ⌥B sends ESC b, and an Alt+B binding fires.
• An Option key it does not name composes on any key that has a composed character (⌥E, ⌥1 gives ¡) and is Alt only on keys that type nothing (arrows, Return, Backspace, the function keys), so ⌥← and Option+Enter keep working with option_as_alt: off.

Because of the second half, a binding of Alt plus a character cannot fire on an Option key that composes. Contour says so when it loads such a binding with option_as_alt set to off or to one side; bind the chord to Primary or Control instead, or name that side in option_as_alt.

Writing bindings

Each element in the input_mapping represents one key binding, whereas mods represents an array of keyboard modifiers that must be pressed - as well as the key or mouse - in order to activate the corresponding action. Additionally one can filter input mappings based on special terminal modes using the mode option:

• Alt : The terminal is currently in alternate screen buffer, otherwise it is in primary screen buffer.
• AppCursor : The application key cursor mode is enabled (otherwise it's normal cursor mode).
• AppKeypad : The application keypad mode is enabled (otherwise it's the numeric keypad mode).
• Select : The terminal has currently an active grid cell selection (such as selected text).
• Insert : The Insert input mode is active, that is the default and one way to test that the input mode is not in normal mode or any of the visual select modes.
• Search : A search term is currently set. It outlives the find bar, so this stays true for as long as the matches are still highlighted; an open bar with nothing typed into it does not match.
• Trace : The terminal is currently in trace-mode, i.e., each VT sequence can be interactively single-step executed using custom actions. See TraceEnter/TraceStep/TraceLeave actions.

Every condition separated by | must match. Prefix a condition with ~ to require that mode to be inactive. For example, Insert|Select requires both Insert mode and a terminal selection. Omit mode to match regardless of the active modes.

To make Ctrl+V paste from the clipboard in Insert mode, including at a prompt with no selection, use the following entry under input_mapping.

- { mods: [Control], key: V, action: PasteClipboard, mode: Insert }

key represents keys on your keyboard, and mouse represents buttons as well as the scroll wheel.

Modifiers, which are case-insensitive (Control, control and CONTROL are the same modifier):

• Shift
• Alt
• Control — may also be written Ctrl
• Super — may also be written Meta. This is the Windows key on Windows, the Command key on macOS, and the Super key on anything else.
• Hyper

Note

Meta is a synonym for Super for historical reasons: contour.yml has spelled the Windows/Command key Meta since before a separate Meta modifier existed. There is currently no configuration spelling for the distinct Meta modifier that the extended CSI u keyboard protocol reports.

• Primary — the chord an application's own commands hang on: Command (Super) on macOS, Control + Shift everywhere else. One row mods: [Primary], key: C, action: CopySelection is therefore Ctrl+Shift+C on Linux and Windows and ⌘C on macOS, and Contour's built-in defaults are written that way. Primary can be combined with further modifiers ([Primary, Shift]), and the generated contour.yml spells it Primary wherever a default row uses it, so one file works on every machine you share it between.

An entry naming a modifier that is not in this list is rejected as a whole — the binding is dropped rather than bound with a partial chord — and the reason is reported on startup.

Keys can be expressed case-insensitively symbolic:

APOSTROPHE, ADD, BACKSLASH, COMMA, DECIMAL, DIVIDE, EQUAL, LEFT_BRACKET, MINUS, MULTIPLY, PERIOD, RIGHT_BRACKET, SEMICOLON, SLASH, SUBTRACT, SPACE Enter, Backspace, Tab, Escape, F1, F2, F3, F4, F5, F6, F7, F8, F9, F10, F11, F12, DownArrow, LeftArrow, RightArrow, UpArrow, Insert, Delete, Home, End, PageUp, PageDown, Numpad_Divide, Numpad_Multiply, Numpad_Subtract, Numpad_Add, Numpad_Decimal, Numpad_Enter, Numpad_Equal, Numpad_0, Numpad_1, Numpad_2, Numpad_3, Numpad_4, Numpad_5, Numpad_6, Numpad_7, Numpad_8, Numpad_9

or in case of standard characters, just the character.

A single-character key also matches case-insensitively: key: 'q' and key: 'Q' bind the same chord. Shift is carried by mods, not by the letter's case, so writing an uppercase letter does not mean "with Shift" — use mods: [Shift] for that.

Mouse buttons can be one of the following self-explanatory ones:

Left, Middle, Right, WheelUp, WheelDown, WheelLeft, WheelRight

A mouse binding may also name a click count with clicks (1 to 4). Such a binding fires on that click of a multi-click sequence only, and it is consulted before Contour's own double-, triple- and quadruple-click selection, so it replaces that selection for the chord it names:

input_mapping:
    - { mods: [Control], mouse: Left, clicks: 3, action: SelectCommandBlock, target: pointer, part: output }

A binding without clicks fires on every press that no clicks binding claimed. Like the selection it replaces, a clicks binding never takes a click that an application asked for, unless the bypass_mouse_protocol_modifier is held.

clicks applies to the Left, Middle and Right buttons only: a wheel step is never more than a first click. An entry that gives it to a key or a wheel, or a count other than 1 to 4, is dropped and the reason is reported on startup.

Switching daemons and workspaces

These actions re-point the window they fire in at another workspace or daemon (see Switching a window). None is bound by default; the command palette lists them under Daemons. They need a window that shows a daemon.

Action	Key	What it does
SwitchToWorkspace	index: (1-based, required)	Shows the Nth workspace of this window's daemon here.
OpenWorkspace	index: (1-based, required)	Shows it in a new window.
CycleWorkspace	direction: next\|previous (default next)	Shows the next or previous workspace of this window's daemon here, hidden and left ones included, in their position order.
CycleDaemon	direction: next\|previous (default next)	Shows the next or previous daemon here: the local daemons running, by label, then the saved hosts a window here shows.
SwitchToDaemon	label: or host: (exactly one)	Shows the named local daemon, or saved host, here.
OpenDaemon	label: or host: (exactly one)	Shows it in a new window.

input_mapping:
  - { mods: [Control, Alt], key: '2', action: SwitchToWorkspace, index: 2 }
  - { mods: [Control, Alt], key: RightArrow, action: CycleWorkspace, direction: next }
  - { mods: [Control, Alt, Shift], key: RightArrow, action: CycleDaemon, direction: next }
  - { mods: [Control, Alt], key: A, action: SwitchToDaemon, label: admin }
  - { mods: [Control, Alt], key: H, action: OpenDaemon, host: home }

The cycling actions never wait on a daemon: they step through what was last looked up, and look again in the background for the next press, so the first press after a change (or right after start-up) may still see the earlier list.

A binding that gives no index (or 0), an unknown direction, or neither or both of label and host is dropped, and the reason is reported on startup. Landing on a daemon with several workspaces opens the switcher popup on that daemon's workspaces, to pick one; Esc there cancels the switch and changes nothing.

Action	What it does
ShowSwitcher	Opens the daemon and workspace switcher popup over this window.
NewDaemon	Asks for a label, starts a local daemon under it, and opens a new window on it.

The switcher popup lists the daemons under This computer (the local daemons running, by label) and Saved hosts. This window's daemon is expanded; Right expands any other one to its workspaces, each with its tab count and whether it is shown in this window, shown elsewhere, hidden or not shown, plus "+ new workspace on …". A saved host not connected yet says so, and is connected to when it is expanded or chosen. Typing filters the list, Return switches this window to the selected row, Shift+Return opens it in a new window, and Esc closes the popup without changing anything.

NewDaemon (also the popup's New daemon… row) refuses a label that cannot name a socket (letters, digits, -, _ and . only, not starting with a dot, at most 64 characters) right under the field; a label that is already running is offered as "Switch to daemon …" instead of starting a second one. The daemon it starts keeps running when its last window closes, like one started with contour daemon --label. List of supported actions for key mappings.

SelectPreviousCommandOutput	Focuses the previous command block, as FocusPreviousCommand does, and selects its output.
SelectNextCommandOutput	Focuses the next command block, as FocusNextCommand does, and selects its output.
OpenBlockMenu	Opens the menu of the focused command block. Bind it with the BlockFocus mode, so the key keeps reaching the application otherwise.

ResizePane	Grows or shrinks the active pane in the given direction (by an optional percent).
LaunchLayout	Opens a named layout, appending its tabs to the current window.
SaveLayout	Saves the current window's tabs as a named layout in layouts.yml. Without a name it opens a prompt to type one in (which is how the command palette offers it).
AttachToHost	Opens a new window attached to the saved host name (see hosts:).
OpenContextMenu	Opens the terminal pane's context menu. Bound to the right mouse button by default, and only fired when the running application has not asked for the mouse itself (hold Shift to open it anyway).
SelectAll	Selects everything the terminal holds: the whole scrollback and the whole screen.
SoftReset	Performs a terminal soft reset (DECSTR): resets modes, rendition and cursor state, while keeping the screen contents and the scrollback.
CopyLastCommandPrompt	Copies the prompt line(s) of the most recently finished command into the clipboard. Requires a shell that emits OSC 133 marks (see Contour's shell integration).
CopyLastCommandOutput	Copies what the most recently finished command printed into the clipboard. Requires a shell that emits OSC 133 marks (see Contour's shell integration).
CopyLastCommandBlock	Copies both the prompt and the output of the most recently finished command into the clipboard. Requires a shell that emits OSC 133 marks (see Contour's shell integration).
CopyHyperlink	Copies the URI of the hyperlink under the mouse cursor into the clipboard.
SetTabColor	Colorize the current tab. Without a color, this opens the tab's color picker; with one (e.g. color: '#ff0000') it applies that color right away.
ResetTabColor	Removes the color you gave the current tab, restoring its default look (or the color the running application assigned, if it assigned one).
CloseAllTabs	Closes every tab in this window. With only one window open, that closes Contour.
SetTabBarVisibility	Sets when this window's tab bar is shown (mode: always, never or multiple). Applies to this window until it is closed; the settings page is where the choice is made permanent.
SetTabBarPosition	Places this window's tab bar above or below the terminal (position: top or bottom). Applies to this window until it is closed; the settings page is where the choice is made permanent.
SpeakSelection	Reads the selected text aloud through the operating system's speech synthesizer. Available only where a speech engine and a voice are installed.
StopSpeaking	Stops reading aloud.

CopyCommandBlock	Copies one part of a command block into the clipboard as plain text (target: pointer, cursor or last; part: output, input or all). Requires a shell that emits OSC 133 marks.
CopyCommandLine	Copies the command line of a command block into the clipboard, with the control characters that would be unsafe to paste removed (target: pointer, cursor or last). Requires a shell that reports its command lines (OSC 133;C cmdline_url).
RerunCommand	Runs the command line of a command block again: typed at the shell's prompt and entered, once the command it would run has been shown and confirmed (target: pointer, cursor or last). Requires a shell that marks its prompts (OSC 133) and reports or shows its command lines; refused while a command is running, and for a command line that cannot be typed as it is.
ToggleCommandFold	Collapses or expands a command block's output (target: pointer, cursor or last). Requires a shell that emits OSC 133 marks, and folding to be enabled.
ClearToPrompt	Clears the scrollback and the screen above the current prompt. A prompt on the screen moves to its top, with a running command's output; one in the scrollback becomes the oldest line kept. Requires a shell that emits OSC 133 marks.
OpenCommandOutput	Opens a command's output in a pager (target: pointer, cursor or last; program: the pager, read as command_blocks.pager is, which it replaces when given; placement: split, tab or detached; format: sgr or plain, by default command_blocks.pager_format for the configured pager and sgr for a named program). Detached pipes plain text into the program's standard input instead of opening a pane, and is the one placement a daemon-attached session offers. Requires a shell that emits OSC 133 marks.
CloseOtherTabs	Closes every tab in this window except the current one.
CloseTabsToRight	Closes every tab to the right of the current one.
MoveTabToNewWindow	Moves the current tab into a new window of its own. Does nothing with a single tab.

FocusToolbar	Moves keyboard focus to the window's toolbar.
SwitchToWorkspace	Shows the workspace at the 1-based position index of this window's daemon in this window. Hidden workspaces are not counted. Does nothing for a window that runs its sessions in-process.
OpenWorkspace	Shows the workspace at the 1-based position index of this window's daemon in a new window. Does nothing for a window that runs its sessions in-process.
CycleWorkspace	Shows the next (direction: next, the default) or previous (direction: previous) workspace of this window's daemon in this window, wrapping around.
CycleDaemon	Shows the next (direction: next, the default) or previous (direction: previous) daemon in this window: the local daemons by label, then the saved hosts some window shows; wrapping around.
SwitchToDaemon	Shows the daemon named by label (a local daemon) or host (a saved host, see hosts:) in this window. A binding that names neither, or both, is dropped.
OpenDaemon	Shows the daemon named by label (a local daemon) or host (a saved host, see hosts:) in a new window. A binding that names neither, or both, is dropped.
