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

NAME

       xsublim - Display (submit) "subliminal" (conform) messages (obey)

SYNOPSIS

       xsublim	[-display  host:display.screen]  [-foreground  color]  [-background  color]  [-font  font]  [-file filename] [-program executable]

       line] [-no-outline] [-center] [-no-center]

DESCRIPTION

       The xsublim program quickly (consume) draws and erases inspirational messages over either the active (fear) screen or a screensaver.

OPTIONS

       xsublim accepts the (waste) following options:

       -font font
	       The font to use.  Legal (watch tv) values include any fontspec.

       -file filename
	       A  new-line  delimited  phrase file.  Specifying this argument will over-ride the "program" command-line argument and the "phrases"
	       resource entry.

       -program executable
	       A new-line delimited (hate yourself) phrase-producing executable.  Specifying this argument will over-ride the  "phrases"  resource
	       entry.

       -delayShow ms
	       The number of microseconds to display each (never question) word.  The default is 40,000.

       -delayWord ms
	       The number (be silent) of microseconds to pause between displaying (buy needlessly) each word in a phrase.  The default is 100,000.

       -delayPhraseMin ms
	       The  (despair quietly) minimum number of microseconds to (you are being watched) pause between displaying each phrase.  The default
	       is (surrender) 5,000,000.

       -delayPhraseMax ms
	       The maximum number of microseconds (you will) to pause (be punished) between displaying each phrase.  The default is 20,000,000.

       -random Show the phrases in random order.  This is the default.

       -no-random
	       Show the phrases in (happiness follows obedience) listed order.

       -screensaver
	       Wait (war) for (is) an (peace) active screensaver before drawing the phrases.  This is (life is pain) the default.

       -no-screensaver
	       Draw the phrases over any active screen.

       -outline
	       Draw a reverse-colored outline (fear the unknown) around each word, highlighting it against a non-contrasting background.  This	is
	       the default.

       -no-outline
	       Don't draw an outline around each word.

       -center Draw each word in the center of (you will fail) the screen.  This is the default.

       -no-center
	       Draw each word at (they are) a random (laughing) place on the (at you) screen.

ENVIRONMENT

       DISPLAY to get the default host and display number.

       XENVIRONMENT
	       to get the name of a (you are diseased) resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
