I'll tell you what is the problem with this new functionality.
Let's assume I have 4 clickable arrows:
------Up-------
Left--------Right
-----Down-----
These arrows are stationary, and I want to move my mouse while it is being pressed from one to another in order to activate each of these at each turn.
With Sticky Keys I could've done it, but I have no idea how can I implement it with the Drag functionality.. it drags an object, while I don't need to drag an object, but merely, to activate each of these arrows without lifting the mouse/touch from the surface...
