Hi to all,
I’m Germano from Italy.
I’m writing a simple application in elisp, and I need to assign some key
bindings, using left window key as key modifier.
I hope this is the correct place for my question. If not, can you point
me in some direction?
I tried some solutions found on internet, but none seem to work.
I’ve emacs 25.1.1 on Windows 10 64 bit.
I do:
(setq w32-pass-lwindow-to-system nil)
(setq w32-lwindow-modifier ‘super)
Now, pressing left window key doesn’t open cortana. This is ok.
I tried to set, for example, win+j to a simple function that display a
message.
(global-set-key (kbd “s-j”) ‘hello)
Doesn’t work. Win+j is not assigned on Windows, so it should work fine.
I tried “s-f9” and it works!
I read on internet someone used autohotkey but I don’t know how to use it.
Some suggestions?
An other question: can be capslock and insert key be used as modifier Keys?
Thanks!

It works for me on Windows 7, so it's probably specific to Windows
10. I think you will have to use Emacs 26 (from the master branch of
the development code), where Emacs can hook the keyboard at a lower
level, and thus intercept key combinations that Windows doesn't
otherwise let us see. I think you will need to use
w32-register-hot-key, as explained in the manual.

You will see in the manual that setting w32-enable-caps-lock to nil
will let CapsLock produce the symbol 'capslock', which you can then
bind as any other function key. As for <insert>, you can make the
keypad Insert key produce 'kp-insert', if you turn off Num Lock.
(Sorry for delay in answering.)

As Eli suggested you will have to try Emacs 26. Apparently, some things
have changed with key bindings on Windows 8/10 and Emacs 25 doesn't cope
with them any more.

Unfortunately, for me Emacs 26 breaks autohotkey support on Windows XP.

Perhaps we should have a command-line option to turn off hooking the
keyboard at low level. We already have the code to do that when Emacs
is started under a debugger (because the keyboard hook affects the
debugger as well), so we just need to do the same under that new
option.

... which BTW breaks debugging code that does use w32 keys, something
which always worked in the past and the reason why I have not yet closed
bug#23163 ...

Hooking the keyboard is tricky. And Windows seems to have changed
policy a number of times in this regard.
