I second the request! 
I wouldn’t stop displaying the shortcuts though, I think both the name and the shortcut should be able to be displayed.
Also, I’d like to request two new shortcuts: “go to next custom brush” and “go to previous custom brush”, that way we could also be able to navigate between brushes using shortcuts no matter how many we have (right now when you have more than 50 you won’t be able to remember all the shortcuts XD).
On a slightly related note, I made some extra dithering patterns for the gradient tool, if you are interested you can find them here: New pattern fill / new dithering matrix
