How about a variable Zoom!

Thanks for that tip. I never clicked and dragged in that little section before. Yes that works as a variable zoom. I always just clicked on it and it brought up a small window that I would then type a number into for the zoom factor. Thanks so much markw.

space + shift + drag (on mac os) does what you're looking for.

Oh, good catch nekomata I had completely forgotten about that key combo! Just too used to using the wheel one my tablet!
