As far as I know, sc does not support this kind of capturing key events. A notable exception is Alt+PF1, Alt+PF2 and so on for switching the virtual terminals which is "handled interally" (by the console driver itself) and won't be available to text mode programs. Maybe /usr/src/sys/dev/syscons/syscons.c reveals the magic, which probably involves ioctl()... > Then what about getting vt's display to look like sc? Not possible, as it seems. This has been discussed recently. There are too many "moving parts" within vt and in the surrounding tools. Essentially, text mode is dead. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
