quick search in dired

[notbob]

I've been using dired in emacs for awhile, it being my fave file mgr.
Somewhere way back in dim past, seems I recall a function where if I
was viewing a dir (v) and wanted to jump ahead to, say, the t's, I
could just hit t and the cursor would at least jump ahead to the
beginning of the t's.  I can no longer can do this.  Am I thinking of
another file mgr or jes having another senior moment?  ;)
