In Gtk, can I make a Button's mnemonic not require an "alt" mask?

Question

I have 6 Buttons, labeled "_0" through "_5". I would like for each button to be pressed when the user presses the corresponding number key. Right now, they must press Alt + the corresponding number key.

I can sort of work around this by giving each button an Accelerator, but it's not quite the same thing. With accelerators, as soon as the key is pressed, the button's Clicked signal is triggered. With mnemonics, the button becomes depressed when the key is pressed, and the Clicked signal isn't triggered until the button is released. I prefer this, because it helps the user to see what is happening.

Is there any way I can get the behavior of Mnemonics, but without requiring the Alt key?

You can have the gtk window catch key events with the event mask settings in the window class. I can't be much more specific than that with callbacks and key types, because I use GTKmm (C++ bindings) but the approach should be similar. Basically when you catch the required key event in your window you can call the button press in code. The window has be to selected (in focus) however.
