# CloseCurrentTab Closes the current tab, terminating all contained panes. If that was the last tab, closes that window. If that was the last window, wezterm terminates. ```lua return { keys = { {key="w", mods="CMD", action="CloseCurrentTab"}, } } ``` *Since: 20201031-154415-9614e117* `CloseCurrentTab` was changed so that it requires a boolean `confirm` parameter: ```lua return { keys = { {key="w", mods="CMD", action=wezterm.action{CloseCurrentTab={confirm=true}} } } ``` When `confirm` is true, an overlay will render over the tab to ask you to confirm whether you want to close it. See also [skip_close_confirmation_for_processes_named](../config/skip_close_confirmation_for_processes_named.md). If `confirm` is false then this action will immediately close the tab and terminates its panes without prompting.
