The KEYBOARD TEST (Boot with ALT, press 3) is not really a keyboard test.
It is a blank screen with an activated (MEGAPHONE) on-screen keyboard that happens to highlight keys when you press them. But it will work badly for RESTORE (no real key) and it will light up RSHIFT if UP or RIGHT are pressed (because there are no UP and RIGHT keys, only shifted DOWN and LEFT).
So we should just add a note to the keyboard test screen that explains this.

Better solution: write a real keyboard test.
