Creating Your First AutoHotkey Script
Now that you’re acquainted with AutoHotkey, let’s create your first script. We’ll begin with a simple “Hello World” script, a perfect starting point for understanding AutoHotkey’s scripting language.
1. Start by creating a project folder on your Desktop. In this guide, the folder is named /ATA.
2. Navigate to the folder in File Explorer. Right-click in an empty area, choose New -> AutoHotkey Script, and name your script, such as HelloWorld.ahk.
Your newly created AutoHotkey script, HelloWorld.ahk, should now appear in your folder, ready for scripting!
3. Open the HelloWorld.ahk file in a text editor of your choice. Initially, it’s a blank slate, ready for you to start scripting in AutoHotkey.
As you progress through this tutorial, keep working on the same script (HelloWorld.ahk) without removing its basic structure.
4. Add the following AutoHotkey code at the bottom of the HelloWorld.ahk file. This script will bind a simple message box to the Ctrl+K hotkey combination. After adding, save and close the file.
This code creates a MsgBox displaying “Hello World! This sample provided by ATA!!” when you press Ctrl+K (^k::) on your keyboard.
^k::
MsgBox, Hello World! This sample provided by ATA!!
ReturnChoose a key combination that doesn’t conflict with existing shortcuts. For instance, Alt+Tab is commonly used by Windows to switch between applications, so it’s not recommended.
5. Right-click on the HelloWorld.ahk file and choose Run Script from the context menu to execute your AutoHotkey script.
Ensure that the default application for AHK scripts, like Notepad, is used for editing and not for executing scripts, or the ‘Run Script’ option won’t appear in the context menu.
Once the script is running, you’ll notice the AutoHotkey icon (a green square with the letter ‘H’) in your system tray. This indicates your script is active and functioning correctly.
6. Test the functionality of your script by pressing the Ctrl+K hotkey. A message box with your custom message should appear.
7. Now, let’s modify the HelloWorld.ahk script. Replace the previous code with the following, which captures the mouse cursor’s position and displays it in a MsgBox. Additionally, it shows a ToolTip with custom text near the cursor.
Save and close the file after adding this new script.
^K::
MouseGetPos, xpos, ypos
MsgBox, The cursor is at X%xpos% Y%ypos%.
ToolTip, Hello World! This sample provided by ATA!!, xpos, ypos ReturnToolTip in AutoHotkey is a versatile feature that displays a brief message near the mouse cursor, enhancing user interaction in GUI-based scripts.
8. To apply your changes, right-click on the AutoHotkey icon in the system tray and choose Reload This Script. This step is crucial for ensuring the updated script takes effect.
Always remember to reload your scripts after making changes to ensure you’re working with the most current version.

Effective Use of Comments in AutoHotkey Scripts
Creating your first AutoHotkey script is exciting, but it’s crucial to make your code clear and understandable. Comments in AutoHotkey scripts are essential for adding context and explanations, making your scripts easier to read and maintain.
Comments are ignored by the script interpreter but are invaluable for collaboration and future reference. In AutoHotkey, comments begin with a semicolon (;) and extend to the end of the line. They can be placed above or inline with commands and functions.
Remember to add a space before the semicolon when placing comments inline with commands. This prevents the AutoHotkey interpreter from mistaking your comments as part of the command, avoiding errors.
; Example of a comment above a command
MsgBox, Hello, world!
MsgBox "Hello, world!" ; Example of an inline commentTo practice adding descriptive comments in AutoHotkey scripts:
1. Edit your HelloWorld.ahk file again. Replace your existing code with the below script that includes comment lines. Save your changes and close the file.
; Demonstrating the use of comments in AutoHotkey scripts
; This sets Ctrl+K as a hotkey (Ctrl is represented by ^)
^K::
; Send command types "Hello" in the active window (like Notepad), followed by Enter
Send Hello {enter}
; Pauses the script for one second (1000 milliseconds)
Sleep 1000
; End of script example with comments
Send Holla {enter} ; Types "Holla" to the active window.
Sleep 1000 ; Waits one second before continuing.
Send Bonjour ; Sends the text "Bonjour" to the active window.
Return ; Ends the script.2. To implement your script updates, reload the HelloWorld.ahk script.
3. Execute the updated script by pressing Ctrl+K. The script will now sequentially print “Holla” and “Bonjour” with a one-second delay, demonstrating the effect of your comments.
Temporarily Disabling Code in AutoHotkey Scripts
While scripting with AutoHotkey, sometimes you need to disable sections of your code temporarily. This could be for testing specific parts of a long script without running the entire thing.
Instead of adding a semicolon to each line, AutoHotkey offers a more efficient method. The /**/ comment style allows you to disable entire blocks of code easily. This style comments out everything between /* and */, making it ignored by the interpreter.
1. Open the HelloWorld.ahk file and use the /**/ comments to disable a specific code block. Save the file after making these changes.
; Ctrl+K hotkey setup
^K::
Sleep 2000 ; Pauses for two seconds
/* Disabled code block
Send Hello {enter}
Sleep 1000
Send Holla {enter}
Sleep 1000
*/
Send Bonjour ; Only sends "Bonjour"
Return ; Ends the script
2. Reload the HelloWorld.ahk script for the changes to take effect.
3. Test the script by pressing Ctrl+K. The script will only execute the “Bonjour” command, confirming the disabled code block is being ignored.
Mastering the Sleep Command in AutoHotkey Scripts
Send Holla {enter} ; Types "Holla" to the active window.
Sleep 1000 ; Waits one second before continuing.
Send Bonjour ; Sends the text "Bonjour" to the active window.
Return ; Ends the script.2. After updating your script, be sure to reload the HelloWorld.ahk file to apply the new changes.
3. Test your script by pressing Ctrl+K. The script will sequentially type “Holla” and “Bonjour” with a delay between them, demonstrating the practical use of AutoHotkey commands and comments.
