- Ctrl does not affect symbol lookup
- Shift inverts NumLock behaviour [X11]
- Shift turns NumLock off, but not on [Win] (FIXME: fake Shifts also sent)
- CtrlL+AltR fake release [Win]

- Ctrl+AltGr+any (FIXME: broken on Win)
- "Shift press, A press, Shift release, A release" should not send "a release"

- Keys are released on loss of focus

is usually variants of these:
