         To create disabled submenu, pass an empty sequence for the command.

         To enable hotkey, insert an underscore before the character,
         e.g. hotkey of 'Item te_xt' is 'x' key.

         To add shortcut key text at the right side of the item, append it at the end of
         the item text, separated by "more than" sign, e.g. 'Item text>Ctrl-T'.

         To insert separator line, pass 0 for the whole item.
