Why are there two  + I shortcuts in preview? I'm used to using Preview for simple edits to images - cropping, censoring, highlighting, rotating - and I try to use shortcuts as much as possible. Previously I would use Cmd + I to show the inspector. A while ago I noticed it wasn't working. Upon further investigation I noticed that Cmd + I also invoked the Show/Hide Toolbar command.

Why are there two shortcuts for the same menu command, and is there any way I can change this for my macs I use regularly?

This is OS X 10.11.6, if it matters. Preview 8.1 (877.7).







Edit to add info: I have no app defined keyboard shortcuts except for "help", see below screenshot...
