For some reason the Mac gods decided that Home and End scroll your window to
the beginning and end of file respectively. This is just wrong. They should
move the cursor to the beginning or end of the line it's on, just like they do
in every other modern UI. Thankfully, there's a way to fix this for all Cocoa
apps, which for me is everything I use!
First you need to make a subdirectory called KeyBindings in your
~/Library directory. Next, use your favorite text editor to create
a file in that directory named DefaultKeyBinding.dict containing
this text:
{
"\UF729" = "moveToBeginningOfLine:"; /* Home */
"\UF72B" = "moveToEndOfLine:"; /* End */
"$\UF729" = "moveToBeginningOfLineAndModifySelection:"; /* Shift-Home */
"$\UF72B" = "moveToEndOfLineAndModifySelection:"; /* Shift-End */
}
Restart any Cocoa apps (Safari, Mail, or TextEdit) to see the new keybindings
take effect!
For more info on this method of binding keys see this OS X
hint and this
Apple document. The commands like moveToEndOfLine: are
actually “Action methods” of the NSResponder
Cocoa class.
