Microsoft Windows only. No install required.

TL;DR: For each text expansion, add a line in your AutoHotkey script file of the form ::abbrev::text to expand “abbrev” into “text” whenever you type it. (Be sure to save the file & reload it in AutoHotkey after you make your change.) Grab a book to learn how to show/hide windows, and launch programs quickly or read more or more.

Step by Step Instructions for Expanding Text


Step 1: Install, no admin required: Install AutoHotkey (even without admin rights). It’s available free-of-charge from AutoHotkey.com. Detailed instructions available here.

Step 2: Open the script for editing: Assuming you’ve followed my instructions, open your AutoHotkey script file for editing by pressing Shift-F5. If you didn’t follow my steps, find the green “H” icon in your Windows taskbar and right-click on it, and click ‘Edit This Script’.

Step 3: Create text expansion: Insert a basic text expansion such as

::hw::Hello World

on a blank line of the file and save it.

Step 4: Refresh AutoHotkey: Reload the file by pressing Ctrl-F5 (if you followed my instructions) or by right-clicking on the green “H” icon in your taskbar and selecting “Reload This Script”.

Step 5: Test your expansion: Now you should be able to type ‘hw’ into any text field and have it expand to ‘Hello World’, once you press the Space or Enter key.

AutoHotkey Text Expansion Reference

Basic Text Expansion

The basic form of text expansion with AutoHotKey is two colons, followed by the abbreviation you want to use, followed by two more colons, followed by the text you want to replace the abbreviation with:

::abbreviationlt::Here is some really long text that will appear whenever I type 'abbreviationlt'. In real life I'd use something like tahke for Tortured AutoHotKey Example.

When you use this form of abbreviation AutoHotkey expects you to type an ending character to indicate that you have completed typing and that, yes, you finished typing an abbreviation that you expect AutoHotkey to expand.

However, sometimes you want AutoHotkey to expand text right away, as soon as you type an expansion trigger (a ‘hotstring’ in AutoHotkey parlance).

Advanced Expansion

By default, AutoHotkey does not expand text right away (in case your hotstring happens to be part of a word) and waits until you type an ending character (such as a space, a right paren, or press the Enter key, etc.). However, you can have AutoHotkey expand your text as soon as the text you’re typing matches a defined abbreviation (your ‘hotstring’), if you’re not in the middle of a word:

:*:rightnow::Expand this text RIGHT AWAY please, AutoHotkey.

This is the same form we used above – with the exception of an asterisk between the first set of colons. The form is a colon, followed by an asterisk, followed by a colon, followed by the abbreviation you want to use, followed by two colons, followed by the text you want the abbreviation to expand into.

If you want AutoHotkey to expand text even if that text occurs as part of a word then you should use define your abbreviations as follows (add a question mark between the first set of colons):

:?:lain::Expand me even in the middle of a word that contains the text 'lain' eg. the word 'explain', which would become really long.

If you want AutoHotkey to expand text no matter what, then you should define your abbreviation this way (use a question mark AND an asterisk):

:?*:always::Always expand this hotstring, even if I'm in the middle of a word OR if I don't type an endchar; just always expand this text whenever you see it.
