It used to be that you could find a Magnify item in the Format menu of the Mathematica front-end, at the very bottom if I remember correctly. You could get at the item in Windows by a keyboard sequence like Alt-R, M, then a number. Mac probably had something similar.

This was really useful for mouse avoiders like me. That little tiny drop menu in the extreme lower right of a notebook is annoying to catch with a mouse on highest-speed setting, which you need on a high-def screen with 1920 or 2560 pixels width. My mouse movements end up looking like a plot of a strange attractor swirling around the target!

I haven't been able to find the Magnify menu item in Mathematica 8 nor any other keyboard shortcut for notebook-magnify in the Mathematica documentation center. Would be grateful for anyone pointing out any means for accessing notebook magnify from the keyboard.

Have you tried Alt-W M ? – b.gatessucks Apr 30 '12 at 14:32
Ahh, thanks. That was it! Post as answer and I'll mark it so (just proves I'm blind, and that's why I need Magnify!) – Reb.Cabin Apr 30 '12 at 14:41
Guess why I knew it ! – b.gatessucks Apr 30 '12 at 14:43
Any idea for the mac version of this? On a related issue, would you know how to change the default size of the help window? – chris Apr 30 '12 at 15:06
@chris No and no, sorry. I will check Linux at home tonight. – b.gatessucks Apr 30 '12 at 15:26

The keyboard sequence is Alt-W M on both Windows and Linux. This will open a drop down menu where you can select the magnification.
