I use Fluxbox as my default WM, but I haven't solved this yet: KDE and Gnome (etc.) allow to switch to virtual console by pressing ctrl + alt + F1, F2, F3 and so on. Fluxbox grabs every keypress due to its internal shortcut key detection, and so this key combination can't be used by normal. So, have you any suggestions? If there is a program which can switch to console I can add it to my key-shortcut file.
