Type ROT, look at the autocomplete results, and you can’t tell whether pressing Enter or Space will run RotateCamera or RotateView.
Sometimes the same three letters keep showing two different commands, making it unclear which one will run. Other times the command line and the drop-down agree, and sometimes the drop-down does not highlight anything at all.
It looks like pressing Enter or Space executes the command suggested in the command line, while pressing Up or Down starts moving from the command shown in the drop-down, so your instinct can’t decide what the keyboard interacts with.
In my opinion, the command line and the drop-down should show the same command. Enter or Space should execute that command, while the Up and Down arrows should move to the command above or below it.
I don’t know exactly when this happens, but it happens often enough that I thought it was worth reporting.
