ActivateWindowRelative(delta)

since: nightly builds only

Activates a GUI window relative to the current window.

ActivateWindowRelative(1) activates the next window, while ActivateWindowRelative(-1) activates the previous window.

This action will wrap around and activate the appropriate window at the start/end.

Here's an example of setting up (not very useful) hotkeys to cycle between windows:

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

return {
  keys = {
    { key = 'r', mods = 'ALT', action = act.ActivateWindowRelative(1) },
    { key = 'e', mods = 'ALT', action = act.ActivateWindowRelative(-1) },
  },
}
