[Qt-creator] Missing shortcut for jump to start/end of document?

[Nikos Chantziaras]

In the keyboard shortcuts editor, I can't seem to find entries for 
changing the shortcuts to jump to the start and end of the current file.

I occasionally need to use Creator on a Mac, and am trying to bind 
Ctrl+Home/Ctrl+End for this. I have changed the shortcuts for things 
like begin/end of line, next/previous word, etc, and this is one of the 
last missing pieces.

Is there a way I can change these shortcuts?
