  3. Modify the file to suit your tastes
  4. Run CodeQuickTester to verify that the updated settings are reflected

Compilation instructions

CodeQuickTester supports compilation only when using AutoHotkey_H, which is almost 100% compatible with standard AutoHotkey. To compile CodeQuickTester into a portable exe file, you can follow these steps:

  1. Download a copy of AutoHotkey_H v1
  2. Extract it, and open up the AHK_H version of Ahk2Exe
  3. Choose the CodeQuickTester script file and an appropriate icon (typically, the file Ahk2Exe.ico from the Ahk2Exe directory)
  4. Set the Base File (.bin) to AutoHotkey v1.1.X.Y AutoHotkey.exe (..\Win32w) (or ..\Win64w, just make sure the file ends in .exe)
  5. Click > Compile Executable <
  6. Copy your compiled CodeQuickTester to a computer without AutoHotkey installed to verify that it works correctly (optional)
