None of the past post offer a solution that works. I do not use entourage.I have turned off and on the computer numerous times.
I cannot find a toggle in preference for this. In illustrator it does work, but not indesign.
I also have trouble duplicating object when pressing the option key. I do not know if this is related.
Try to press both Shift+Ctrl
Here are some reasons that modifier keys may not work, and possible solutions:
(1) Fixed by restarting InDesign
(2) Fixed by restoring InDesign preferences.
(3) Fixed by changing System Preferences > Keyboard > Keyboard Shortcuts conflicts (Mac)
(4) Fixed by finding third-party software which is conflicting (utilities or browsers, for example).
