Mauro's Keyboard Shortcuts

What is this used for?

This is a configuration guide to setup my keyboard shortcuts on MAC and Windows.
I am using 60% keyboards with no QMK firmware support.

Windows setup

1. Install AutoHotkey from https://www.autohotkey.com/;
2. Create a file script.ahk and fill with above code:

RAlt::RControl

CapsLock::
  KeyWait, CapsLock
  If (A_PriorKey="CapsLock")
  	SetCapsLockState, % GetKeyState("CapsLock","T") ? "Off" : "On"
Return

#If, GetKeyState("CapsLock", "P") 
  h::Left
  j::Down
  k::Up
  l::Right
  `;::`
  '::~
  /::\
#If

If using v2, use this script instead:

#Requires AutoHotkey v2.0

; Remap RAlt to RControl
RAlt::RControl

; Toggle CapsLock with double press
CapsLock::
{
  KeyWait "CapsLock"
  if (A_PriorKey == "CapsLock") {
      SetCapsLockState GetKeyState("CapsLock", "T") ? "Off" : "On"
  }
}

; Only active when CapsLock is on
#HotIf GetKeyState("CapsLock", "P")

h::Send("{Left}")
j::Send("{Down}")
k::Send("{Up}")
l::Send("{Right}")
`;::Send("{`}")
'::Send("{~}")
/::Send("{\\}")

#HotIf

3. Double click on script.ahk script;
4. Make sure script is running (look for an AutoHotkey icon on windows status bar);
5. Click Win+R, type shell:startup, paste a shortcut to AutoHotKey script here;
6. Or, save script as "C:\Users\mauro\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup\script.ahk";

MAC Setup

1. Install Karabiner Elements from https://karabiner-elements.pqrs.org/ ;
2. Open your karabiner.json file (it will be in ~/.config/karabiner/karabiner.json).
3. Find complex_modifications. It will have a key rules that takes a list ("rules": [...]).
4. Inside the square brackets, paste this:

                  {
                      "description": "Caps Lock + I/J/K/L to Arrow Keys, Caps + ; and ' to ` and ~ ",
