>Description:
The syscons console driver has a special key to switch to the next
virtual console but none to switch to the previous console.
The appended patch adds this missing functionality. Files touched:
sys/i386/include/console.h console driver symbol PREV
sys/dev/syscons/syscons.c actual functionality
usr.sbin/kbdcontrol/lex.h internal symbol TPREV
usr.sbin/kbdcontrol/lex.l map "pscr" to TPREV
usr.sbin/kbdcontrol/kbdcontrol.c tie "pscr", TPREV, and PREV
>How-To-Repeat:
For testing purposes, I created a keymap with the switch previous/next
screen special keys on cursor left/right:
