Support "shift + home" and "shift + end" on mac

Issue

I press shift + cmd + "arrow right" ( shortcut:shift + end ) in the texteditor and nothing happens.
I want all text to the end to be marked (and to start when using home).

I use this when I to copy or replace lines in the editor.

OS X 10.11.1
Sonic Py 2.9

Also just cmd + "arrow right" and cmd + "arrow left" to move to the start/end of the lines. I'm having a ball with Sonic Pi, but this is driving me a bit nuts: I didn't realize how much I used it!

As an update on this, I know it can be annoying but configurable keybindings is surprisingly difficult to implement well. I'm not saying it will never get done, but it's not top priority at the moment.
