Superscript and subscript keyboard shortcuts

[cookiemonster]

The default keyboard shortcuts for superscript and subscript are Ctrl+Shift+Plus key (numeric keypad), Ctrl+Shift+Minus key (numeric keypad).
I sometimes use a keyboard without a numeric keypad so I added extra shortcuts for them to also use Ctrl+Shift+Equals and Ctrl+Shift+Minus.
But it would be nice if these keyboard shortcuts came by default.
