The mouse sensitivity issue should hopefully be fixed in the new version. Thank you for reporting it!
It's tricky to rotate even-sized bounding boxes in place in a way that's reversible without using Undo, and I'd also like to maintain consistency with Home/End. I'm also not sure about conditionally entering Move mode, given that pressing Enter/Space while not in that mode would start executing the solution.
Now that mouse sensitivity has been lowered, please retry using the Ctrl+E - PgUp/PgDn - Enter sequence; if it's still too much of a hassle, I can consider having PgUp/PgDn/Home/End + modifier key (Shift or Ctrl) perform an implicit Ctrl+E.
