What is AutoHotkey, and What is it Used For?

AutoHotkey is a free scripting language designed to automate tasks within the Windows operating system. It's especially useful for those who often perform repetitive actions or use complex key combinations. With AutoHotkey, you can remap keys, create macros to automate clicks and actions in applications, and even run complex scripts that execute multiple operations at once.

Main Features of AutoHotkey

AutoHotkey offers extensive customization and automation options, including:

  • Key remapping and hotkey creation: Easily assign new functions to any key or create combinations that speed up access to specific functions.
  • Routine automation: Use scripts to perform repetitive actions like typing, copying and pasting data, switching between windows, and much more.
  • Macro creation: Record a sequence of actions and replay them as needed, allowing you to complete complex tasks with just one click.
  • Window management and message boxes: Control the behavior of windows, adjust their size and position on the screen, and create interactive message boxes for more flexible script control.

Examples of AutoHotkey Scripts

AutoHotkey scripts can be simple or complex, depending on your needs. Here are a few basic script examples to accomplish common tasks:
