I need to create a keyboard shortcut like "ctrl + h", that hide the menu bar.. is possible do it? and is possible hide a button and cut the window to optimize space? thanks!
Sure.
To hide the menu, it depends on how the menu is incorporated, but in most cases you can just call Hide or Show(false). The same for the buttom.
To catch Ctrl+H: If it is a menu command, it would happen automatically (if you add Key) (but not if menu is hidden).
You can also override Key method and catch it yourself.
