"Please hold down CTRL+ALT and press T" sometimes results in (novice) users holding down all three keys at once.
Desired behaviour:-
One terminal opens, keyboard combination does not repeat.
Actual behaviour:-
Bazillions of terminals launch
On my Ubuntu 16.04 system running Unity, the keyboard shortcut does not repeat. On 17.10 GNOME Shell it does. I believe it should not. See screenshot.

It gets worse. The terminals may open when you're pressing nothing: bug 1707828 :)
This sounds like a reasonable enhancement with respect to shell shortcuts. But also consider multi-key combos like Ctrl+C that should (or at least do conventionally) autorepeat.
