Windows has a feature called mouse keys. Is there any way to make it use other keys?
For example rather than use the numberpad I'd rather use QWE/ASD/ZXC instead of the 789/456/123 that it comes with.
I'm interested particularly in modern versions of windows (7/8/10)
This is slightly different from this question as that solution isn't easy to toggle; with the built in mouse keys you can toggle the keys on/off with NumLock but for that answer you have to logout/reboot for it to take effect.
