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:"; 
}

Save (using the shortcut “Ctrl + o”) and exit (“Ctrl + x”) the file.
Restart your Mac. The “Home” and “End” should be working now, and you can use it in conjunction with the “Shift” and “Ctrl” modifier buttons.
