## Example of using this software.  In your startup script referenced by your 
#.desktop file you only need to include 3 lines to implement this script.
#Here is how you could map the AUX key to F5:
#
# . omkey_functions
# 
# om_key_mod 177 F5
#
# run_my_sweet_app
# 
# om_key_restore
#
#And that's it!  Several global variables will be used (all beginning with omkey_*)
#to save keymap info.  So, be careful not to step on those.
#

om_key_mod () {

  # Declare some local variables
  local AUX_KEYCODE i MAP_KEY retval

  # 1st argument is the hardware keycode for the AUX button, should be 177
  AUX_KEYCODE="${1}"

  # 2nd argument is the new key to map AUX to
  MAP_KEY="${2}"

  # Save current AUX Key mapping
  omkey_xmod_save_key="$(xmodmap -pke | grep 'keycode ${AUX_KEYCODE}')"

  # Detect if we are running Enlightenment
  if [ ${E_IPC_SOCKET} ]; then
    # Find the enlightenment key bindings for AUX
    for i in `enlightenment_remote -binding-key-list|grep Keycode-${AUX_KEYCODE}`; do
      case $i in
        CONTEXT=*) omkey_er_context=${i#CONTEXT=} ;;
