ID CC. I turned off ALL shortcuts in mac os prefs. C-\ no longer invokes indent to here. Is there another shortcut somewhere that's conflicting? Thanks.
Working for me in Mac OS X 10.8.5 and InDesign CC 9.1 (latest release).
Check your InDesign keyboard shortcuts (Edit > Keyboard Shortcuts).
Or try it in a new user on your computer to see if a third party application is taking it over.
