Feature Request: make Shift/Ctrl work with the keyboard for control bar (as they do for mouse clicks)

[itteerde]

The modifiers Shift/Ctrl for Advantage/Disadvantage should also work when not mouse-clicking the control bar, but using the numbers on the keyboard. This would be very useful for DM running groups of enemies (drag combat features once, fight with a few number keys, Shift and Ctrl after that), and for players using spells with many repeated rolls such as Scorching Ray upcasts.
