Maybe not exactly what you requested; but you can toggle quantize on/off with the T shortcut key.
Great, that works too. While resizing a clip and hold the left mousebutton pressed, I can still press T, thats great!
SHIFT/ALT/CTRL would be a just a more common way for any action while the mousebutton is already pressed. But nevermind, different programs, different shortcuts, I just have to get used to it. Thanks 🙂
