(Edited the above post to removed the last paragraph, which wasn't quite correct. Correct info:)
You can also use accelerator keys. These depend on language and may also depend on when your config was made, but if you push Alt and T to open the Tools menu, a key will be underlined which you can push to access that menu item.
For me, it was D which conflicted with another item in the menu, but that was because my toolbars are old/edited. On a new English config, it will be M, but the keys are assigned when the menu is generated to avoid them clashing with each other, so they may vary from config to config.
You can edit those by moving/placing an & before a character in the menu item's label. Accelerator keys are in addition to hotkeys. You can have both, neither, or either.
