Re: It's the IT sixth sense
So the tab key is a couple of right-facing arrows
On my Cherry 3000, the tab key has left- and right-pointing arrows as well as the word "Tab". Backspace and shift also bear text as well as the somewhat appropriate arrows.
I'm not sure about the Model M, but those are only used by True Aficionados who know what each key means (even though they've probably remapped it), why it's called that and its keyscan code. Mere punters don't use them, especially since they don't have flag and menu keys, so explanatory text (which they won't read anyway) is irrelevant..
