Magic Keyboard (Mac) make home/end button to move begin or end sentence like window.

 

The solution

The only solution is to change my keyboard so I don’t have to change me.

1. Open Terminal in MacOS
2. Type the following commands, one per line:

cd ~/Library
mkdir KeyBindings
cd KeyBindings
nano DefaultKeyBinding.dict

The top part is what your Terminal should look like

3. Next, copy and paste the below key mapping into the editor that shows:

{
/* 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:"; 
}

In the editor, paste the above key mappings

4. Then save the file by pressing Control ^ + o then Control ^ + x to exit.

5. Restart your Mac for the changes to take effect.
