yeah, I get you barber, acrobat really is a bloated pos that fails to address the most basic glitches since several main versions...but I rely on it to edit pdfs... adding comments and such really isn't fun with preview...can't remember anymore but there was another killer problem with it last time I tried it...
I do have that keybrd shortcut defined and enabled, it works on other non-apple software...but on acrobat pro 10 shift-cmd-d invokes the 'delete pages'-dialog... and there's no way to change keybrd shortcut in acrobat (how **** arrogant is that on top of ignoring standards)
now I thought that maybe changing the 'look up in dict' shortcut would help as it would solve the conflict with acrobat's 'delete pages' shortcut, but no...
I've tried David's logbook solution, but under acrobat, 'no services apply' still stands.
