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, 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.action

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