Home and End Buttons sending different signals on Keypress - How to fix

[kc2npu]

^{Originally posted by **kc2npu** July 26, 2023} I am new to this and found an article online that mentioned that Karabiner as a potential tool that I can use to resolve my situation. I use Microsoft Remote Desktop on my MacBook Pro (Ventura 13.5) to access my office desktop (Windows 10 Pro Education 22H2) via our VPN. If I use Apple's Magic Keyboard the Home and End keys on the keyboard function as expected - moving the cursor to the start or end of the current line in Windows. However, if I use the Rii RK801 Wireless Bluetooth Keyboard with the laptop and press the Home or End keys it docks the window I am working on to the left (home) or right (end) of the screen and shows me other windows which can be tiled on the other half of the screen. Using the KeyCodes app and the Karabiner-EventViewer, it was determined that the keyboards are sending different signals for the keypresses: | Key Pressed | Apple MagicKeyboard | Rii RK801 Wireless BT | | ----------- | ------------------- | --------------------- | | [HOME] | **KeyCode App**

]| How do I get Karabiner help to "remap" the Rii Keyboard to actually do what the Apple MagicKeyboard sends. Especially since the Rii Keyboard appears to be sending two keypress signals instead of just a single one.

I was able to write a json file and put it into the complex_modifications folder to add the following rules
