how to edit multiple pages at once

Hi.

Is it the cartoon mouse in the upper right that you wish to edit on all pages?  Will this PDF be distributed, or will it be printed?  If printed, you could make a blank button in the forms tools, and then right-click and choose "Duplicate across pages" to apply your "white patch" on all pages.  This could work best if the file was to be printed.  If to be distributed, you end up with a 'buttoin' that if found, one could click... and it would do nothing anyway.  It's clumsy - but might work in a pinch.

If the desired edit is not that graphic, please give us as many details as you can - maybe someone can come up with an idea to help.

My best,

Dave
