- Actually, I did find some mention of this key in a Desktop manual.
- It's called "Meta" (shades of Stanford and CMU early '70s, still reflected
- in Emacs manuals) and indeed is another "shifter" key.

- I'm even more certain of this now that the Meta key's purpose is known.
-
- Now it's up to Mentors remaining programmers to fix their Xwindows
- interface so oddball mouse events don't hang the system.

- Heh heh. The Sun physical designers beat this one -- they put the spring
- (a rubber cup) inside the keytop, so if you yank a key, it often
- sticks *closed*. Guess you have to destroy the conductive rubber membrane
- below the key too, and hope nobody ever needs it. Bad for resale value.

- I understand that Mentor grew up on Apollo Aegis/Domain and the port
- to XWin (OpenWindows) is just that, a port.
- Still would like any hints anyone can give.
