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.

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