Re: a scratch course on virtual folder usage

[Rodrigo Amestica <ramestica@nrao.edu>]

many many thanks Vitaly. I'm doing much better now.

in the process of trying your suggestions I came to notice that we
also have 'g' (wl-summary-toggle-disp-msg) This function is what I was
missing to fully exploit the matching criteria on the fly. Even better,
what ever I type remains in memory (M-p)

many thanks,
 Rodrigo
