I'm using Indesign CC 10.1 on a Mac.
A couple of days ago the usual Alt+pull (to copy an object) + Shift+pull to shift an object, just stopped working.
I've reseted my preferences files, only to make the problem worse. None of the usual commands that work together with the mouse function any more.
Copying, pasting, printing etc still works fine.
Reinstalling is not really an option; I won't have access to the network at work for at least a month.
Typically caused by some other program or the system stealing the shortcut.
Can another program steal those commands inside Indesign when all the other usual commands work? I've experiences "command stealing" before, but I thought it was a problem that was gone years ago :-)
Unfortunately the answer seems to be yes.
