Hi. VNC is working perfectly for me. In particular I appreciate the means by which I can 'nest' my fvwm2 Window Managers. I typically scroll around virtual desktops by using control-arrow key sequences. If the numlock key is ON then these sequences are ignored by the WM of my physical desktop session and passed through to the session I have running in my VNC viewer. It's brilliant! :-)
The mailing list archive has an entry from Mark Rainford posted back in 2004; the URL in the archive is: http://www.realvnc.com/pipermail/vnc-list/2004-February/043069.html He wrote: > Sure, two sets of hot keys would be a dusty road to nowhere nice.

I'm delighted by this feature, even though I think I found it by accident; despite Mark's saying that the trick is 'often mentioned' I don't think it was too easily found when I was looking. Associated with that I'd like to know why the numlock trick works ... is this something that was deliberately done by the VNC developers? I'm unfortunately ignorant of how X11 works; does the X server pass the key sequence to the primary WM, which ignores it - because it doesn't have a binding for numlock+<the rest> - and then it (the WM) passes it on? Does the WM strip off the numlock, or does vncviewer remove it when it receives the event? Is this something I can find documented in Xorg manuals or is it a VNC eccentricity? It works great for me, I'm just curious! If there's any documentation or standards out there regarding this 'trick often mentioned' I'd appreciate references! Oh, one quick secondary question; this 'numlock pass-through' doesn't work if I'm running vncviewer with the -FullScreen option. Which isn't a problem, as I was able to do a workaround; use fvwm2's 'Style' declarations to have a full-size viewer stripped of its WM decorations while still enjoying the numlock-passthrough functionality. My novice question - does vncviewer 'totally grab' the keyboard - have first look at events - when it's running with -FullScreen? But the WM gets the key events first when vncviewer is running without that option?
