The icing on the cake is to get Control-K working. You can do this with a macro. Go to Tools » Macro » Macros. Set the macro name to CtrlK, then click Create. When the macro window appears, add the following lines just before the End Sub line:
Selection.EndKey Unit:=wdLine, Extend:=wdExtend
Selection.Cut
Hit the W icon on the toolbar to save the macro and go back to Word. Now go back to the Tools » Customize » Customize Keyboard window, choose Macros from the Categories pane, and assign your new macro to Control-K.
