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.

return {
  keys = {
    {key="w", mods="CMD", action="CloseCurrentTab"},
  }
}

Since: 20201031-154415-9614e117

CloseCurrentTab was changed so that it requires a boolean confirm parameter:

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.

If confirm is false then this action will immediately close the tab and terminates its panes without prompting.
