Advantage is that people already know about Magic Pavel> Sysrq and know how to disable it. (It would be something like Pavel> Sysrq-E, you can't really use esc). Pavel This discussion is strange. Nigel is right, if one starts suspending by mistake, one wants to be able to abort it easily. 'Esc' is just the perfect key for that. What's the point of hiding or obscuring it? I mean, why would you want to do that? You don't routinely 'hide' Ctrl-C for security reasons, do you? =2D-J. --=-=-= Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (GNU/Linux) iD8DBQA/EME5Lth4/7/QhDoRAgy+AJ4mNKdyjZk4VvDObQJYO/+YIXFxSQCfZlWf 7C48wvu9Z1BmpGXk0G6ClU0= =dGVf -----END PGP SIGNATURE----- --=-=-=--
