Initial Comment:
I would like to know if existsted any trick for the GNU screen program.

I do not know any: it would be nice to complete screen command line with both a list of names of the started screens and their full identifier (eg. 23442.abcde)

The list afaik is gotten through '/bin/screen -l'

The completion would result in 'screen 23442.abcde' in case user writes 'screen abc[TAB]' or 'screen 234[TAB]'

It be useful to integrate it, would not it?

Message:
AFAIK a more simple approach to whis would be to tweak the sed-expression in _screen_sessions() a bit:

have screen &&
_screen_sessions()
{
    COMPREPLY=( $( compgen -W "$( command screen -ls | sed -ne \
        's|^\t\{1,\}\([0-9]\{1,\}\.\)\([^\t]\{1,\}\).*'"$1"'.*$|\1\2\n\2|p' )" \
        -- "$cur" ) )
} 

Instead of:
12345.pts-1.somehost
This writes:
12345.pts-1.somehost
pts-1.somehost

(And is a much smaller change)

Cheers,
  Johannes

I was wrong, it existed the function to reattach / detach existing screens. The available list is from screen -ls.

It currently does not complete the second part of the screen name, eg: for 23442.abcde , only matches for completion the first part of the screen name, i.e. 23442. If even typing abc[TAB] would complete with 23442.abcde

I made a patch for this. With it it is possible to only remember begin of the screen name, the completion will take care of the rest.
Also fixed with the patch, not completing the possible screen name when -r or -R s not the latest option passed.
