steve, i mean it's always worked for me regardless of the tool i'm
currently in. Does it work in that fashion for you in both cs6 and CC. i am
running that OS and the computer was just set up today. something i'm doing
wrong and i can't figure out the difference between home and work inDesigns
both working on brand new imac27's
Usually the lack of Modifier shortcuts indicates interference from some other software; either the OS itself as in Spotlight shortcuts or something like a Firefox or Chrome addon which interfers with using the Cmd-Space shortcut to zoom.
Larry is probably correct.
Go to System Preferences > Keyboard > Shortcuts. Check the shortcuts for Spotlight. It's probably grabbing your shortcut.
thanks, gents, that did the trick.
very much obliged...
