Switch xbmc and console

[GloW]

Hello

With a standard computer, i used to ctrl-alt-fX to switch between x server and console.

But with xbmc, i need to close it using the close button in interface before reaching the console.

So here my questions :

Is there a way, during boot time, to interrupt xbmc starting and go directly to console ?

In console, is "service xbmc start" the right way to launch xbmc ?

Is there some kind of ctrl-alt-f2 with xbmc to switch between xbmc and console ?

Is there is keyboard shortcut to close xbmc at any time (like ctrl-alt-backspace with xorg )

many thanks
