Configure (Home and End) Keyboard Keys in M2 Air

[anjanesh]

I switched from my 2018 Intel MacBook Pro Mojave to 2022 M2 MacBook Air Sonoma and disconnected my 2018 Magic Keyboard and Magic Mouse and Magic Trackpad from the former to the latter.

But my Home and End keys are acting as Page Up and Page Down respectively. How / Where do I fix these ?

I got it working from this blog post.

sudo bash
mkdir -p ~/Library/KeyBindings ; cd ~/Library/KeyBindings
vim DefaultKeyBinding.dict

{
/* Remap Home / End keys */
/* Home Button*/
"\UF729" = "moveToBeginningOfLine:";
/* End Button */
"\UF72B" = "moveToEndOfLine:";
/* Shift + Home Button */
"$\UF729" = "moveToBeginningOfLineAndModifySelection:";
/* Shift + End Button */
"$\UF72B" = "moveToEndOfLineAndModifySelection:";
/* Ctrl + Home Button */
"^\UF729" = "moveToBeginningOfDocument:";
/* Ctrl + End Button */
"^\UF72B" = "moveToEndOfDocument:";
/* Shift + Ctrl + Home Button */
"$^\UF729" = "moveToBeginningOfDocumentAndModifySelection:";
/* Shift + Ctrl + End Button*/
"$^\UF72B" = "moveToEndOfDocumentAndModifySelection:";
}
