Hello, I don't know if I'm in the right group.  I'm a relatively new
user to Emacs and I was wondering how I would do a search and have it
delete the specific text.  if someone could help me out, I would really
appreciate it.  Thanks, Mindy

Interactively:    M-x replace-regexp RET <some-regexp> RET RET

Programmatically: (while (re-search-forward "<some-regexp>" nil t)
                     (delete-region (match-beginning) (match-end)))

Yes, you are in the right group!

Emacs is said to be (among others) a "self documenting" editor. This
is, in fact rather close to reality. I personally would recommend to
every new user to install a relatively new version (what contains the
full documentation by default) and start using C-h.

E.g. in your case:
* C-h i -> opens the documentation (Info)
* don't forget to read the "intro" on the top of the page: it describes
  the most basic keys in an info window
* go to "Emacs" (second link) (and Enter)
* go to Concept Index
* search for "replace": C-s replace
* repeat C-s until you find what you need. In this case it can be:
"* global substitution:                   Replace."
Here (chapter 20.9) you see how to query replace, regexp replace, etc...

Well, you already need some Emacs-specific keys for these steps, but you
will remember them quite soon ;-)

You can check what a key would do by:
C-h k <here do the key sequence or mouse event>

C-h b shows all usable keys in the active window.

And C-x k closes ("kills") the unnecessary windows...

Well, first   C-h t    for the tutorial where replace-string is mentionned.

Pascal has already given you the most general solution to your problem,
but if you don't want to get into regular expressions yet and if you
haven't changed the default, out-of-the-box key assignments, then just do:

M-< (press Alt-Shift-< at the same time to go to beginning of buffer)
M-% (press Alt-Shift-% at the same time) and see
Query Replace: [Here type the text to be deleted]
Query Replace [text] with: [Here press Return (Enter)]
Press space bar at every instance of [text] to be deleted and N for those
instances to be retained.
If after deleting a few instances you are sure you want to delete all the
rest, just press Shift-!
