MoveTabRelative

Move the current tab relative to its peers. The argument specifies an offset. eg: -1 moves the tab to the left of the current tab, while 1 moves the tab to the right.

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

return {
  keys = {
    { key = '{', mods = 'SHIFT|ALT', action = act.MoveTabRelative(-1) },
    { key = '}', mods = 'SHIFT|ALT', action = act.MoveTabRelative(1) },
  },
}
