I find equation entry on lyx rather nice (being a long-time latex user), but editing leaves something to be desired. I find it almost impossible to mark, cut and paste parts of equations. Almost every time I try, I wind up selecting the whole equation and starting over.
If you do selection with the mouse then I strongly suggest to use the keyboard instead (with the shift key modifier and the arrow keys). Mouse selection is quite touchy indeed but you should obtain exactly what you want with the keyboard.
