Dear developers,
In the documentation there's said, that lyx only uses Shift (S-), Control (C-) and Meta (M-) as modifiers, I would appreciate it if its possible to make the "window-keys" on an 105-key-keyboard (Super_L, Super_R and Menu) work as modifiers, too - at least optional.
There are two problems: first these keys have to be configured as modifiers and make LyX use them.
Unfortunately, LyX does not (yet) support alternate keys modifiers. This would not be difficult to code, but nobody found the urge to do it yet. A nice small project for somebody, maybe?
As you see my answer is not very useful. This is probably the reason why you did not have an answer the first time.
