In Windows, you can use & to tag menu items, & will put an underscore under your menu item and will execute when you press the key you associated it with (the character after the ampersand).
so if you tag a menu item as "E&xit" and if you press X when File menu is open, your program will exit.
That's not the case with Actions menu. It does not work. As seen below,
My menu item "(&1) Trim title → Filename Track. Title" does not work when you press 1 on keyboard.
