The steps to insert new language syntax in sublime 3

1. Change AutoHotkey to open sublime when I right click "Edit this script". Run reg file "C:\1data\RegHacks\DefaultEditor4AutoHotKey.reg" to make Sublime 3 your default text editor.

2. Open Command Palette by either Tools, Command Palette or Ctrl+Shift+P. Enter the command: "Package Control: Install Package" and look for AutoHotKey and choose it. Done!

Note: Some installations may need to have Package Control installed:

1. Open the command palette by Win/Linux: ctrl+shift+p, Mac: cmd+shift+p

2. Type "Install Package Control" then press enter
