Well, in passing, I poked at the VM's a bit more, though nothing useful arises... In summary, it looks as if the Caps Lock key is subject to "special" handling, probably both in X11 itself *and* by the VM. For comparison, the Num Lock key appears to map straight through to xkbvleds (and my own test code) entirely "unmolested" and can be read reliably within the VM. But the Caps Lock shows some unusual features. - With the VBox VM hosted on Win7: I can read the keyboard in "real time" with XQueryKeymap and see the Caps Lock key being pressed and released. I take this to mean that the VM is passing the key stokes through pretty much unmolested on Win7. However, the state reported for Caps Lock (either by X11 or by fltk) does not reliably reflect the "true" state until after the *next* key is pressed (sometimes it is OK, but not often enough to be considered reliable!) This, I *assume* is special handling within X11 in some way. Num Lock is always fine, AFAICT. - With the VBox VM hosted on OSX: When I read the keyboard in "real time" with XQueryKeymap I *never* see the Caps Lock key being pressed and released. It just never seems to get flagged, ever. I take this to mean that the VM is NOT passing the Caps Lock key stokes through at all. I think the Caps Lock state is somehow only coming through to the VM on the next key stroke. As a result, the state reported for Caps Lock (either by X11 or by fltk) does not reliably reflect the "true" state until the *next* key is pressed. So in this case, it would appear there is "special" handling of the Caps Lock key by *both* the VM and by X11. Num Lock is always fine, AFAICT. The end.
