I have a strange behaviour in Acrobat Reader 11.0.3 and Strokes+ 2.7.1
I have assigned two global gestures and actions:
<\ Down> does: acSendKeys("^{PLUS}")
</ Up> does: acSendKeys("^{SUBTRACT}")
equivalent to <CTRL/+> and <CTRL/-> so pretty well everywhere these will zoom in and zoom out of the current application view.
Except in Reader.
acSendKeys("^{SUBTRACT}")
zooms out exactly as expected, but
acSendKeys("^{PLUS}")
does a rotate clockwise – which is <CTRL/SHIFT/+> in Reader
so – in effect, Reader appears to be seeing an extra SHIFT on that particular acSendKeys call. <CTRL/+> from the keyboard works as expected.
Other applications are not seeing that – for example Firefox does nothing (visible) on <CTRL/SHIFT/+> from the keyboard, but does zoom in with the acSendKeys combination, which shows it's not getting the <SHIF>. I have the same gestures firing off different actions in specific applications which zoom on different key combinations, and those work just fine too...
