This is a bug report:
As you likely know you can use Ctrl + arrow keys to move to end of words in either direction. Introducing a new "Smart Action" That was bound to Ctrl + Num6, performing a series of clicks (F2,LeftArrow,Ctrl+Shift+Right*6,Right,Del,Enter,Down) the jump to end of word (Ctrl + Arrows) stopped working reliably (only first click registered, after which ctrl became unpressed). The Smart action was deactivated, so I didn't think much of it, BUT IT WAS THE CULPRIT. It wasn't until later today I deleted it and now my computer works as it should.
