I have seen experienced user who don't even know they can use the tab to move to next field - they just go for the mouse or touchpad for every field. Don't know if they ever ask themselves why is the enter key repeated on the keyboard, and always so close to the numeric keys.

The speed of data entry is seriously degraded since the days of data entry. Now that it's become data tabby or data clicky, it either takes two hands or moving one hand AFK and back for each control... well, that's progress. And progress is, by definition, moving forward. I just think they looked the wrong way when they defined that forward.

>I have seen O or Alt+O on OK so there is a common use what is to be respected - on customers money. I prefer to have ALt+O free for other use.

I have a case where enter doesn't work but alt-o does (file properties in Foobar mp3 player)... go figure
