[mythtv-users] Anyone know what key to use for BBCi "TEXT" key to exit?

[nospam312]

I thought I would give the DVB-T Freeview Interactive feature a try on
my MythTV box and I have Red, Green, Blue and Yellow buttons mapped
and working but BBCi says press the "TEXT" key to exit.  Does anyone
know what key to press on the keyboard for this?  The Escape key takes
you out of Live TV not just BBCi.  Thanks.
