$ cd ~/Library
$ mkdir KeyBindings
$ cd KeyBindings
$ vi DefaultKeyBinding.dict

Put these lines in that file, including the curly braces:

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