SendKey

Since: 20211204-082213-a66c61ee9

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 wezterm = require 'wezterm'
local act = wezterm.act

return {
  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"}},
  }
}
