It's probably easiest to take out the break and put the actual desired action inside the case statement. For readability, you might want to externalize the definition of the action into a function.

Code:
searchonefile () {
  # Replace this with more useful functionality
  grep fnord /etc/motd
}

searchallfiles () {
  # Ditto
  grep fnord *
}

while true; do
       cat <<____HERE

Main Menu: 
Please Select An Option Using The Options Provided.

1 - Search All Files

2 - Search Individual Files

q - Quit

Please enter your option: 
____HERE

        read CHOSEN_KEY

        case $CHOSEN_KEY in
                1)     searchallfiles;; 
                2)     searchonefile;;
                q)      echo " "
			echo "Goodbye"
                        exit;;
        esac
done

install-menu(1) 					      Debian GNU/Linux manual						   install-menu(1)

NAME

       install-menu - Process a menu method and generate the menu files for a window manager or a menu-aware application.

DESCRIPTION

       update-menus(1) computes the list of menu entries and passes it in turn to the menu methods in /etc/menu-methods/. The task of a menu meth-
       ods is to generate menus for a specific window manager.	install-menu provides a generic and customizable way to do that. The documentation
       of the install-menu definition language is available in the Debian Menu manual, a local copy being available in /usr/share/doc/menu/html.

SYNOPSIS

       install-menu [-vh] [--remove] <menu-method>

       Read menu entries from stdin in update-menus --stdout format and generate menu files using the specified menu-method.

       Normally used in menu method scripts as #! /usr/bin/install-menu.

OPTIONS

       -h,--help
	      Show the help message and exit.

       --remove
	      Remove the menu files instead of generating them.

       -v,--verbose
	      Output messages about what the program is doing.

COPYING

       install-menu is distributed under the term of the GNU General Public License version 2, or (at your option) any later version.
