Yes certainly. But the monster is X, not Debian.
Also one of mc's advantages is that it does'nt need X.

Cut & paste is perhaps even more 'got to have' than mc.
But again it's independant of X.
I'm currently installing 'FromScratch' linux via my RedHat6.2
partition; but I don't want to have to startx. BTW in a case
like this I need several mc-s open (in VTs - not xterms) for:
1. read the instructions
2. make a log of notes of my progress
3. navigate around the RH6.2 partiton
4. navigate around the 'FromScratch' partition
5. extra stuff ...
The only thing much better for serious work, than linux with
multiple mc-s, is (free multitasking) oberon - my normal
work-horse.

So how will you fix it ?
I needed this facility yesterday, to find a string in a dir-tree and
had to do it manually ! Also Ctrl O doesn't 'temporarily close' the
mc panels - less problematic.
