Write AutoHotkey v2 scripts for window targeting, hotkeys, and GUI automation

Steps

1. Target a specific window using `WinActivate` with a title or class: `WinActivate('Untitled - Notepad')` or `WinActivate('ahk_class Notepad')` — use the bundled Window Spy utility to find the exact window title and class.
2. Define a hotkey with the `::` syntax: `^!n::` followed by the script body and `return` (or use a function hotkey `^!n:: MyFunc()`) — `^` is Ctrl, `!` is Alt, `+` is Shift, `#` is Win.
3. Send keystrokes to the active window with `Send('{Enter}')` or `SendText('hello world')` for literal text that should not be interpreted as special keys.
4. Click UI elements by position or use `ControlClick` to click a named control without activating the window: `ControlClick('Button1', 'ahk_class MyApp')` targets the control by its class number.
5. Use `WinWaitActive('Window Title')` before interacting to block until the target window becomes active, preventing race conditions when automating sequences that open new windows.
