Key Mapping

To customize key mappings, you need to configure input_mapping yaml entry 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 modes 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 : There is a search term currently being edited or already present.
  • 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.

You can combine these modes by concatenating them via | and negate a single one by prefixing with ~. The modes option defaults to not filter at all (the input mappings always match based on modifier and key press/mouse event). key represents keys on your keyboard, and mouse represents buttons as well as the scroll wheel.

Modifiers:

  • Alt
  • Control
  • Shift
  • Meta (this is the Windows key on Windows OS, ans the Command key on macOS, and Meta on anything else)
    Keys can be expressed case-insensitively symbolic.

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.

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

Left, Middle, Right, WheelUp, WheelDown

CreateSelection, delimiters: '' Creates selection with custom delimiters configured via delimiters member.
DecreaseFontSize Decreases the font size by 1 pixel.
DecreaseOpacity Decreases the default-background opacity by 5%.
FocusNextSearchMatch Focuses the next search match (if any).
FocusPreviousSearchMatch Focuses the next previous match (if any).
FollowHyperlink Follows the hyperlink that is exposed via OSC 8 under the current cursor position.
IncreaseFontSize Increases the font size by 1 pixel.
IncreaseOpacity Increases the default-background opacity by 5%.
NewTerminal Spawns a new terminal at the current terminals current working directory.
NoSearchHighlight Disables current search highlighting, if anything is still highlighted due to a prior search.
OpenConfiguration Opens the configuration file.
OpenFileManager Opens the current working directory in a system file manager.
OpenSelection Open the current terminal selection with the default system application (eg; xdg-open)
PasteClipboard Pastes clipboard to standard input. Pass boolean parameter 'strip' to indicate whether or not to strip repetitive whitespaces down to one and newlines to whitespaces.
PasteSelection Pastes current selection to standard input.Option evaluate_in_shell specify if pasted text must be appended with linefeed and used as an input for the running shell
Quit Quits the application.
ReloadConfig Forces a configuration reload.
ResetConfig Overwrites current configuration with builtin default configuration and loads it. Attention, all your current configuration will be lost due to overwrite!
ResetFontSize Resets font size to what is configured in the config file.
ScreenshotVT Takes a screenshot in form of VT escape sequences.
ScrollDown Scrolls down by the multiplier factor.
ScrollMarkDown Scrolls one mark down (if none present, bottom of the screen)
ScrollMarkUp Scrolls one mark up
ScrollOneDown Scrolls down by exactly one line.
ScrollOneUp Scrolls up by exactly one line.
ScrollPageDown Scrolls a page down.
ScrollPageUp Scrolls a page up.
ScrollToBottom Scrolls to the bottom of the screen buffer.
ScrollToTop Scrolls to the top of the screen buffer.
ScrollUp Scrolls up by the multiplier factor.
SearchReverse Initiates search mode (starting to search at current cursor position, moving upwards).
SendChars Writes given characters in chars member to the applications input.
ToggleAllKeyMaps Disables/enables responding to all keybinds (this keybind will be preserved when disabling all others).
ToggleFullscreen Enables/disables full screen mode.
ToggleInputProtection Enables/disables terminal input protection.
ToggleStatusLine Shows/hides the VT320 compatible Indicator status line.
ToggleTitleBar Shows/Hides titlebar
TraceBreakAtEmptyQueue Executes any pending VT sequence from the VT sequence buffer in trace mode, then waits.

TraceLeave Disables trace mode. Any pending VT sequence will be flushed out and normal execution will be resumed.
TraceStep Executes a single VT sequence that is to be executed next.
ViNormalMode Enters/Leaves Vi-like normal mode. The cursor can then be moved via h/j/k/l movements in normal mode and text can be selected via v, yanked via y, and clipboard pasted via p.
WriteScreen, chars: '' Writes VT sequence in chars member to the screen (bypassing the application).
CreateNewTab Creates a new tab in the terminal emulator.
CloseTab Closes current tab.
SwitchToTab, position: 0 Switch to absolute tab position (starting at number 1)
SwitchToTabLeft Switch to tab to the left
SwitchToTabRight Switch to tab to the right
