This is what I mean:

OK, Just to clarify, I know what it does.

If you put a series of letters/numbers in this column, then when you search commands, it will pop up.

As an example, if I put the letter t for "Open.."

Then, when I type t in the search bar, the first thing that comes up is "Open.."

But here's what I can't figure out.

If I am searching for the Command, "Open" then why wouldn't I just type open?

I guess I understand that if there is something with a long name, like "Hide/Show Feature Manager tree" then this would speed up the search.....but I would first have to go into customize, access keyboard shortcuts, find the item I want, assign the search criteria, then go up to the search bar and type it in.......

That makes no sense to me at all.  I suppose, the first time, I might want to know where it is, but if I can't remember where it is, why would I remember the search criteria for it?

I am just trying to understand this column in the Customize menu and what its practical use is.  Maybe there is some awesome shortcut/speed up thingy that I am missing, and curious minds want to know! 

Does anyone use this functionality?  And if so, what for?
