A nice moment in the iOS emoji keyboard – after selecting an emoji from the grid, its name shows up for a second:

I have small reservations here, as reusing a placeholder like this trips up my “this is cheap” alarm. But otherwise I like that this – just like keyboard shortcuts in menus or tooltips – ambiently teaches you the alternative representation of the emoji that you can use later to get to it faster.

(Another way of looking at it: This is a tooltip in a place where tooltips cannot exist.)
