CHVT(1)

NAME
       chvt - change foreground virtual terminal

SYNOPSIS
       chvt N

DESCRIPTION
       The  command  chvt N makes /dev/ttyN the foreground termi-
       nal.  (The corresponding screen is created if it  did  not
       exist  yet.   To get rid of unused VTs, use deallocvt(1).)
       The key combination (Ctrl-)LeftAlt-FN (with N in the range
       1-12) usually has a similar effect.
