need help with this recoil script

hello everyone, i have been using this recoil script which is working great for me,but i want to upgrade it and i need help, i want to add 2 functions to the script and dont know how.
i would like the scroll lock button to turn on and off when i activate and deactivate the script, and i would like to add an ignore button for grenades use(caps lock would be great for that).

the script is for logitech software
this is the script im using:
^{----------------------------------------------------------------------------------
-------------------------------- control settings --------------------------------
----------------------------------------------------------------------------------
------------------ button 3 - activation/deactivation of SCRIPT ------------------
----------------------- button 4 - recoil minus - STEP 15% -----------------------
----------------------- button 5 - recoil plus - STEP 15% -----------------------
----------------------------------------------------------------------------------
local activated = 3 -- click wheel mouse
local minus = 7 -- click button 4 mice
local plus = 8 -- click button 5 mice
----------------------------------------------------------------------------------
------------------------------ sensitivity setting -------------------------------
------------- inversion - set the "minus" sign before the sensitivity ------------
----------------------------------------------------------------------------------
-------------- the sensitivity setting in the game 50 - change 45-55 -------------
------- the default vertical multiplier in the game is 0.7-change 0.7-1.3 --------
----------------------------------------------------------------------------------
local sensitivity_global = 50 -- sensitivity in the game (default is 50)
local sensitivity_vertical = 1.0 -- the multiplier is vertical (default is 1.0)
----------------------------------------------------------------------------------
------------------- power of the compensating vertical recoil --------------------

i know it's linear and not perfect recoil control, but works great for the first 5 bullets, and the rest is pretty easy to compensate

what program do u use to complie this and how to use it
can u help me
tks <3
