Dired narrowing?

Dired narrowing?

How do I narrow a dired buffer to see only files with a regexp name?

what about M-x find-grep-dired
that would call the following function:

find-grep-dired is an interactive compiled Lisp function in `find-dired'.
(find-grep-dired dir regexp)

Find files in dir containing a regexp regexp and start Dired on output.
The command run (after changing into dir) is

    find . -exec grep -s -e regexp {} \; -ls

Thus ARG can also contain additional grep options.

I someone has a shorter sequence for this, please post it.  I use a
three-command sequence:

'% m' to mark the files you want.  To mark .txt files, the regexp
would be "\.txt" or perhaps "\.txt$" (without the quotes).  ^ matches
the beginning of a file name, not the beginning of a dired line.  To
mark temp* you might do "^temp".

't' to invert the marks, so the ones you *don't* want are marked.

'k' to kill the marked lines (this doesn't delete files, it just
removes listings temporarily from the dired listing).

----------------------------------------------------------------------

'% m' is dired-mark-files-regexp

,----[ C-h f dired-mark-files-regexp RET ]
| dired-mark-files-regexp is an interactive compiled Lisp function in `dired'.

| 
| Mark all files matching REGEXP for use in later commands.
| A prefix argument means to unmark them instead.
| `.' and `..' are never marked.

| REGEXP is an Emacs regexp, not a shell wildcard.  Thus, use `\.o$' for
| object files--just `.o' will mark more than you might think.

| `.' and `..' are never toggled.

'k' is dired-do-kill-lines

| If you use this command with a prefix argument to kill the line
| for a file that is a directory, which you have inserted in the
| Dired buffer as a subdirectory, then it deletes that subdirectory
| from the buffer as well.
| To kill an entire subdirectory (without killing its line in the
| parent directory), go to its directory header line and use this
| command with a prefix argument (the value does not matter).

Shortcut:

Command dired-mark-extension is bound to `* .'.
Use it to mark all files with a particular extension (such as txt).

M-x dired <ret> *.java <ret>

It's a globbing expression, not a regular expression, but it works for me.
