I use SharpKeys on my Windows 8 machine to rebind the Caps Lock key to F13 so that I can use it as a hotkey/modifier in other programs. This works fine in Windows applications--for example, http://keycode.info/ correctly reports that I've hit F13 when I press Caps Lock.
However, this does not seem to work in vcxsrv, which treats the key as KP_Enter, i.e. Enter on the numpad. The output from xev is identical regardless of whether I press Caps Lock or the real numpad Enter key. This behavior is not affected by Num Lock, the -keyhook argument to vcxsrv, or the -xkbvariant nodeadkeys argument to vcxsrv, which is everything I could think to try myself. As far as I can tell this is the only key that is not passed through correctly.
In case it matters, I'm using PuTTY to SSH into a Fedora 28 VM to run the X applications I'm using (like xev).
