GotoFileStart GotoFileEnd - missing keyboard shortcuts

Assign shortcuts for GotoFileStart GotoFileEnd text editor commands and remap HOME/END keys for users accustomed to pc windows shortcuts like HOME/END instead of CTRL + LEFT/RIGHT and CTRL + UP/DOWN instead of HOME/END.

On Mac OS X it is possible to remap HOME END keys using KeyRemap4Macbook (Karabinier) app but Qt Creator does not work in this way. However other mac applications works excellent like xCode, TextEditor etc. but QT Creator has some problem with this. It seems that the only solution is to have a possibility of assigning these key shortcuts inside Qt Creator.

HOME GotoLineStart
END GotoLineEnd
SHIFT + HOME GotoLineStartWithSelection
SHIFT + END GotoLineEndWithSelection

CTRL + HOME GotoFileStart
CTRL + END GotoFileEnd
CTRL + SHIFT + HOME GotoFileStartWithSelection
CTRL + SHIFT + END GotoFileEndWithSelection
