#219 MouseKeyboard object is missing keys

[Snoop Baron]

The mouse and keyboard object is missing some keys. Some of these might be missing due to different keyboard layouts but I think at least some of them are an oversight. I'll list all the missing keys (using standard US keyboard layout) starting with the ones that are most likely missing in error:

Page Up
Page Down
Num pad Enter
-
=
[
]
\ /
.
,
;
'
`

The windows keys are also missing, but they are of course proprietary.
