`SendKey`¶

Since: Version 20211204-082213-a66c61ee9

The functionality described in this section requires version 20211204-082213-a66c61ee9 of wezterm, or a more recent version.

Send the specified key press to the current pane. This is useful to rebind the effect of a key combination.

Note that this rebinding effect only applies to the input that is about to be sent to the pane; it doesn't get re-evaluated against the key assignments you've configured in wezterm again.

For example, macOS users often prefer to rebind Option+LeftArrow and Option+RightArrow to match the behavior of Terminal.app, where those key sequences are remapped to ALT-b and ALT-f which generally causes the the cursor to move backwards or forwards by one word in most common unix shells and applications.

The following configuration achieves that same effect:

local act = wezterm.action

config.keys = {
  -- Rebind OPT-Left, OPT-Right as ALT-b, ALT-f respectively to match Terminal.app behavior
  {
    key = 'LeftArrow',
    mods = 'OPT',
    action = act.SendKey {
      key = 'b',
      mods = 'ALT',
    },
  },
  {
    key = 'RightArrow',
    mods = 'OPT',
    action = act.SendKey { key = 'f', mods = 'ALT' },
  },
}
