Enter key, Transmit, F10, Carriage Return and tab

From CometWiki

There are 2 enter keys: The main key labeled enter at the right of the letters and the enter at the right of the numbers on the 10 key pad.

The enter key could be caused to do one of 3 actions:

1. Act like a tab and go to the next field on the line.
2. Act like a carriage return and go to the first forground field on the NEXT line.
3. Act like an F10 and transmit all forground text in the current input area.
