; A shortcut should be created for this script and placed in the Windows 10
; user's startup folder to automatically enable the feature on boot/startup.
; The user's startup folder can be found using the following steps:
;
; 1. Windows Key+R. The _Run_ dialog will appear.
; 2. Enter the following: `%appdata%\Microsoft\Windows\Start Menu\Programs\Startup`
; 3. Press Enter key. A file explorer dialog will appear.
; 
; Obviously, [AutoHotkey](https://autohotkey.com/) must be installed for this to work.
*CapsLock::
    Send {Blind}{Ctrl Down}
    cDown := A_TickCount
Return

*CapsLock up::
    ; TODO: prevent send {Esc} after another key has been pressed.
    If ((A_TickCount-cDown)<100)  ; Modify press time as needed (milliseconds)
        Send {Blind}{Ctrl Up}{Esc}
    Else
        Send {Blind}{Ctrl Up}
Return

I got the script from https://www.autohotkey.com/boards/viewtopic.php?p=468638&sid=c96c7e48529bc2061a4d6d76eb9616fb#p468638

Not sure why but the script for ahk v1 is more consistent than v2 script.
