[nfbcs] undoing -- me or this program...grrrr

[tribble]

hi all --
I'm on my XP laptop in OE.  I got a little too careless and accidently moved 
several thousand messages from one folder to another -- using the find 
command followed by selecting and moving (control+shift+v)
I hoped upon hope that OE would provide an undo command -- like 
control+shift+z, to undo the previous move, but it doesn't work.
So I painstakingly tried separating  out the mail I moved and put them back 
in my inbox.
(I know, my email activity probably goes beyond what OE is intended for, but 
it is convenient and works for me -- most the time.

So as the subject implies, it's me or OE -- does anyone know of an easy way 
of recapturing messages accidently stuck in the wrong place?
(This requires more than copying time intervals, as the messages are 
interspersed with other messages.)

TIA
