#8 Command+, --> Preferences and Command + arrows mapping

[Anonymous]

I've been using iTexMac2 for a few days now and it's working great for me. I have two request however, namely could you map Command + , (comma) to the Preferences menu item, as is common for a lot of applications. Also, navigation in the tex editor could be enhanced by mapping the Command + arrow keys to Command + --> = End of line and Command + <--- = Begin of line (as is the case in for instance TextEdit and XCode).
Thanks and keep up the good work!
