Add a search field in Customize the Ribbon
It is hard to find commands when you don't know how they are named.
A search box that filters all commands for a given phrase would be very helpful.
E.g. when I enter "shape" in that search box I want to see only commands that contains "shape" anywhere in there name.
This is already supported. In the ribbon, you’ll see a lightbulb icon with the text “Tell me what you want to do.” If you type the command you want to perform there, it will filter all commands (like “Shape”) and show you a list of the relevant ones.
Hope that helps,

I can't even find the lightbulb icon

Sorry, I must strongly disagree, try to find the command for "Select Current Region".
You will not find it because it is not included in the ribbon.
So you have to customize the ribbon and add this command.
Make that and then try to find the command you just added => Fails!
This box did not search the ribbon!
