How to make AHK script activation and deactivation?

Question

autohotkey

Hello! I have a question, there is a script for AutoHotKey:
LButton::
Loop
{
Send, {sc11}
Send, {sc11}
Send, {sc11}
Send, {sc11}
Send, {sc11}
Send, {sc11}
Send, {sc11}
Send, {sc11}
Send, {sc11}
Send, {sc11}
sleep, -1
If !getkeystate("LButton" )
Break
}
Return
it simulates pressing the W(sc11) key when the left mouse button is pressed.
I need the script to start working, for example, when the Insert (sc152) key is pressed, and stop working when the same key is pressed. Also, if possible, to make this script work in a specific application.

This will only work in notepad:
#If WinActive("ahk_exe notepad.exe")
suspend, on
LButton::
Loop
{
Send, {sc11}
Send, {sc11}
Send, {sc11}
Send, {sc11}
Send, {sc11 }
Send, {sc11}
Send, {sc11}
Send, {sc11}
Send, {sc11}
Send, {sc11}
sleep, -1
If !GetKeystate("LButton")
Break
}
Return
#If
Insert::suspend
