Technically, GTK calls these mnemonics, and what it calls accelerators 
are the normal keybindings, which we already display to the right of the 
menu item.

With GTK, the menu item's text contains an underscore before the letter 
which the developer wants to use as a mnemonic. I think lesstif does it 
the same way (I can only find documentation for Motif, which does it 
this way), and in windows, an ampersand is used in the same way. On all 
three platforms, to the user the mnemonic character is underlined, and 
the _ or & does not appear as part of the menu text. From what I've read 
about Mac OSX, mnemonics are not supported, instead it has a completion 
like interface - effectively, the first letter of the menu functions 
like a mnemonic for the first encountered menu item, but menu items 
further down may require two or more keystrokes to access.

Probably the best way to handle this then is for the Windows menu code 
to replace _ in menu item text with &, and for mac, tmm and non-toolkit 
X menu code to strip out the _ (or build the code in to handle it). Then 
we can go through our menus and add _'s as appropriate.
