tmw / togglemainwindow        Toggles special features of 'main' windows

   Format:
      ;tmw                    Shows current special features

      ;tmw -s                 Toggles system messages in the 'main' window
      ;tmw -u                 Toggles 'main' window's urgency hint
      ;tmw -t                 Toggles tooltips in session's default tab

   Notes:
      This command enables or disables some behaviours in 'main' windows.
      The '-s' switch enables or disables displaying system messages in 'main'
         windows. Note that, even when enabled, individual sessions might still
         refuse to display system messages in their 'main' window, for example
         when connected to a world that's using VT100 cursor control sequences.
      The '-u' switch enables or disables the 'main' window's urgency hint.
         When text is received from the world and the 'main' window is not on
         the user's current workspace, the window has its urgency hint set. On
         many systems, the window will start flashing on the workspace panel
         (taskbar). This won't happen if the urgency hint has been disabled with
         this command.
      The '-t' switch enables or disables tooltips in the session's default tab,
         meaning the area of the 'main' window where text received from the
         world is displayed.
