The mouse wheel in the Windows VM also sends Ctrl-up/down events, which is definitely more appropriate than plain up/down events.  (I haven't looked at the VM code, but the scroll wheel has identical behavior to pressing ctrl-up-arrow or ctrl-down-arrow.)  In the image, ctrl-up-arrow has the effect of scrolling a scrollpane up a few lines, without moving the text cursor, which is also what a scroll wheel should do.
