Toggle toolbar with ALT key (like Win7 Explorer)

I think the subject is pretty much explanatory. I need to show/hide a toolbar (specifically the Menu toolbar) by pressing the ALT key, like Windows Explorer does when the Menu is hidden.

Anyone knows if that's possible and how?

Thanks a lot.

You mean a Dopus toolbar? Alt alone isn´t possible, & even if it was, i don´t think that would be a good idea, because many other
combinations are relying on the Alt key combinations, where the Alt is to be pressed shortly before the other keys, like Alt-Tab
or Alt-F4, etc.

You could try something like Alt-Space instead.

You can move the menu items you want to keep, but not see at the top level, into submenus (or context menus), if that helps.
