Would like to move lines up and down with alt + arrow key

Maybe i am missing this featre in scrivener somehow but one of my most used tools in MS Word is the key combination of alt+shift+arrow to move a line of text up or down - especially bulleted or numbered text.

Is this an existing feature that I am overlooking?

If not, is ther a developer kit or embedded language that might allow me to write the functionality?

TIA

The Mac version of Scrivener uses the standard OS X text engine, so it will only do what what Apple have decided that the text engine should do. MS Word has its own text handling built into it, so it will do rather more. You could probably use Keyboard Maestro to achieve the effect, if it is important to you.
