For example, CapsLock::Ctrl makes Caps Lock act as Ctrl while the script is running. To swap two keys, write a remap in both directions. You can also limit a remap to a particular window with #HotIf.
Make a basic key remap
These examples use AutoHotkey v2. Add a version requirement to the top of the script so the intended major version is clear:
#Requires AutoHotkey v2.0
CapsLock::CtrlSave the text as a plain-text file with the .ahk extension, then run the script. While it is active, pressing Caps Lock behaves as pressing Ctrl. The general form is OriginKey::DestinationKey: the key on the left is the one you press, and the key on the right is the behavior it produces. See the AutoHotkey remapping reference for syntax and behavior details.
For ordinary letters, lowercase examples such as a::b allow Shift and Caps Lock to determine letter case in the usual way. Check the key names and syntax against the AutoHotkey version you have installed; v1 and v2 scripts are not interchangeable in every respect.

Swap two keys instead of remapping one
A single line changes only the key on its left. To make A produce B and B produce A, define both directions:
a::b
b::aWith only a::b, pressing A produces B, but pressing B still produces B. The second line is what makes the mapping a two-way swap.

Run, test, and change the script
- Create the script: Put the version directive and remap lines in a plain-text
.ahkfile. - Run it: Launch the script, then test the remapped key in a harmless text field before relying on it in other applications.
- Adjust it: Edit the remap and reload or restart the script as appropriate for your installed version.
- Turn it off: Exit the running script to stop its remappings.
AutoHotkey remaps are active only while the script is running. Installation and automatic startup steps can vary; check the official AutoHotkey site for current setup and launcher guidance rather than assuming a particular startup procedure.
Apply a remap only in a particular window
Use #HotIf to make a remap conditional on the active window. This example limits a::b to a window whose class is Notepad:

#HotIfThe final, bare #HotIf restores the default context for remaps that follow it. The example’s window identifier is not universal: identify the class or other window details for the application you want to target before using a condition.
What to expect from a remap
- Modifiers carry through: Held modifiers such as Ctrl or Shift generally affect the destination. For example, under
b::a, Ctrl+B behaves as Ctrl+A. - Holding and repeating: The destination is held while you hold the source key, and remapped keys normally repeat while held.
- Compatibility varies: Some applications and games may not handle remaps as expected. AutoHotkey implements remaps as pairs of hotkeys, with hook-hotkey and input-mode caveats; no method here guarantees support in every program or on every screen.
If a remap does not work, first check that the script is running and that its syntax and key names match your AutoHotkey version. If those are correct, the target program may intercept keyboard input in a way that prevents the remap from working as expected.

AutoHotkey or PowerToys Keyboard Manager?
AutoHotkey is a script-based option; Microsoft PowerToys Keyboard Manager provides a graphical interface. Choose based on whether you need window-specific conditions, whether you want to configure mappings through a GUI, and whether you need shortcut or text remapping. Both rely on a running program or utility, and compatibility depends in part on the target application.
| Consideration | AutoHotkey | PowerToys Keyboard Manager |
|---|---|---|
| Configuration | Write remaps in a script. | Add a mapping row in the graphical Keyboard Manager interface. |
| Window-specific mappings | Use #HotIf to condition a remap on the active window. |
Different mappings for different connected keyboards are not supported; app-specific mapping behavior is not established by the cited Keyboard Manager documentation. |
| Shortcuts and text | Not covered by the basic key-remap examples here. | Microsoft documents remapping keys, shortcuts, and text. |
| Must remain running? | Yes. The script must be running for its remaps to remain active. | Yes. PowerToys must remain running in the background with Keyboard Manager enabled; Microsoft says changes take effect immediately. |
| Compatibility considerations | Some applications and games may not handle remaps as expected. | Microsoft documents limits involving reserved shortcuts, Fn, the login screen, elevated apps, games, certain keyboard APIs, and shortcut keypress order. |
PowerToys-specific restrictions
In PowerToys Keyboard Manager, create a mapping row, select the input and output, and apply it. To stop those mappings, disable the utility or close PowerToys. Microsoft’s Keyboard Manager documentation, last updated June 8, 2026, lists these restrictions:
