Transfers control to another place in the script file. This is useful for managing control flow for looping, and in response to timeout branching. Usage example:
on error: $Not There
timer: 30
wait for: abc<CR>
goto: $Got It
$Not There:
;failed to see it, send Ctrl+C
send: <3>
goto: $bad
$Got It:
;turn timer off because we got abc<CR>
timer: 0
;more commands ...
