In CS4, the option key only navigates artboards if you have the artboard tool selected (shift-O). Maybe the same in CS5?
Thanks for responding Doug, and I think your probably right that you need the artboard tool active (which is pretty pathetic for navigaton purposes), but even then it's halfbaked. Say I have 3 artboards and I'm zoomed in on No.1, hitting 'shift-O' then 'option-arrow' merely moves the focus but fails to actually take you to the newly 'selected' artboard! for that you would need to then hit 'command-0' to re-centre on the new artboard!! What a piece of cr*p! I was merely looking for a way to cycle through artboards using a keyboard shortcut... sigh!
Pl. don't abuse the application before even exploring its features. Illustrator CS5 has added tremendous capabilities to the Multiple Artboards feature introduced in CS4.
No, you DO NOT need to activate the Artboard tool for navigation. Simply press Shift+PageDown or Shift+PageUp to navigate between artboards.
You have a keyboard shortcut of Opt/Alt+Cmd/Ctrl+0 to 'Fit Artboard in Window'.
Pl. refer to the Help documentation to know about various features.
I hope the OP marks your response as the answer
Thank you for the answer and I'm sorry if I upset your sensibilities, but it is very frustrating when one DOES read the help files and finds incorrect information (please read my original post again re- pg 34 of the said help files).
All the best
