The HELP key is just a fast way to enter the HELP command. I would guess applications could re-map it to their own internal HELP systems but I don't know.
Just shows how little time I've spent with the C128. Gotta remedy that! The Mega65 also has a HELP key that does the same.
What is the Mega65 interpreter based on?
Did they go with Commodore BASIC 7, or extend BASIC 2 with a few extras, or is it wholely its own thing?
@notawizard It's BASIC 10.0 from the official C65 ROM (licensed, with improvements). I gather it's mostly the C128's BASIC 7 with nine more commands, and the Mega65 team added a few more to control the virtual disk stuff from a BASIC program (MOUNT, DIR, BACKUP, possibly others, and an Easter egg).
And actually at first glance of that screenshot, the colours and the narrow text made me think it was an AmigaBASIC screen. :)
