I've discovered that there is a +/- zoom tool... however it only shows up when my Acrobat is set up as in tabs (not individual windows).
(Preferences > General (left side) > Check box: Open Documents as new tabs in the same window (requires relaunch)
Personally I don't like the tabs if I need two window side by side.. although separating them is another nuisance.
But the +/-/% is possible to be shown. I just don't know what causes this.
