adjust movement speed by scrollwheel

I know that scrolling is for zoom, and that should never change.

BUT: What if somebody is pressing (for example) "alt" + scroll (up or down) at the same time, and it would adjust the move speed? (Maybe I'm overlooking this option, or perhaps there is another way for this) In VR but also in general, it is slightly annoying to get out of the movement to adjust movement speed so to speak.

Keep up the good work!!

To clarify: I think what I sort of wish is a way to increase or decrease movement speed without number punching.
