The Meta key is from the Symbolics culture,
Yes, and just like HYPER and SUPER they come in pairs. One on the left and one on the right.
the 2 diamond keys from the Sun culture are Super.
No, SUN diamond is
META.
I think with OS-keys you mean the Windows keys, right?
More in general really, I mean
COMMAND on Apple
META on SUN
WINDOWS on M$
SUPER on X
There is no MENU key or equivalent on Apple or SUN.
On M$ there is a MENU key (they invented it) and X uses it by default too (xev showed me).
So I think the vast majority of us actually "need" a MENU key.
And IMHO having only one META key doesn't do any justice to the great great Space-Cadet.
Currently, there is no MENU key at all.
Indeed. But love to see it in the standard-layouts ...
Sun layout is: Caps Lock, Alt, Super (diamond) and Super, Compose, Alt Graph.
My SUN type 5/5c/6 kbds all have: control, alt, meta, meta, compose, alt graph.
I'm typing on a type 6 now.
If you take 2 of the Modifer kits, I will add another WINDOWS key and the MENU key!
No no no, no windows(key) for me ! That's definitely NOT what I'm after.
The MENU key however ...
Too bad I'd have to take a MODIFIER set for it, makes it a rather expensive key.
Please (re)consider
META > MENU in STANDARD
and
WINDOWS > META in MODIFIER
Please be patient ...
No hurry --- thanks for all you do to make this possible
