A downloadable tool for Windows

What it KeyMapper?

Simply put , It's free software  for remapping keys on Windows !
it works like this : Press D on your keyboard and the game/app will recieve G instead, All Inputs* apart from Left and Right Click can be mapped into other keys,
Easy to use and offers a bunch of nice features !

What it’s for?

  • Keep different key layouts per game/app.

  • Fix missing/awkward laptop keys.

  • Create ergonomic layouts for editors, CAD, stream decks.

  • Auto-swap mappings when you switch windows / apps

  • RDFG or ESDF users  ( created for that reason first ! )

What it does

  • Map any key or mouse button to another key or mouse button.

  • Link your mappings to Profiles you can save for different apps

  • Per-app filter: make a profile apply only to a chosen .exe.

  • Auto-switch profiles based on the active process.

  • Add Notes to your mappings (handy for complex sets / games).

  • Configurable Params :, start-with-Windows, hide-on-minimize,language menu via the tray icon (16 langs),

  • Stores settings in %AppData%\KeyMapper\KeyMapper.ini. Portable and lightweight, doesn't need admin rights if you have a work machine / family machine

  • Key mapping are disabled on Keymapper itself so you don't have to keep track on what key you switch or want to mep , it's all default keyboard keys

Can you add a feature that lets you select letters from a dropdown menu? my w key is broken and i cant remap the key to another for games that don't allow changing keybinds

I certainly will ! that's a good idea I haven't thought of that , I'll work on that today and get back to you with a new version :D
