Hiding files in dired ?

Hiding files in dired ?

[David Masterson]

I'm aware of dired-do-kill-lines hiding all marked files in the current
directory buffer.  My question is how to combine the (multiple) marks
and kill into one key.  I suppose I could combine several
dired-mark-files-regexp and the kill into a macro, but I was wondering
if there is something more elegant (flexible?).

Side question: where is the syntax for Emacs regexp documented?

In the manuals, of course.  Each one of the two manuals has a chapter
which documents that.

Not clear to me what you're asking.  Are you asking
how to both _mark_ multiple files and _act_ on those
that are marked, with one key?  There are zillions
of different ways of marking files.

You also have other ways to hide files:
`dired-hide-all' - all subdir listings
`$' - one subdir listing
`dired-omit-mode' - files matching regexp or extension

The Elisp manual.
