# ActivateLastTab *Since: 20210404-112810-b63a949d* Activate the previously active tab. If there is none, it will do nothing. ```lua return { leader = { key = 'a', mods = 'CTRL' }, keys = { -- CTRL-a, followed by CTRL-o will switch back to the last active tab { key = 'o', mods = 'LEADER|CTRL', action = wezterm.action.ActivateLastTab, }, }, } ``` See [ActivateTab](ActivateTab.md) for a way to activate a tab based on its position/index.
