I had try to put a box on a formula to emphysise it and to add a Label so i could use the cross reference in th future. For this i done the following:
\fbox -> C - m -> C - enter.
Note - C stand for Control.
I added C - enter to be able to add a label for cross reference.
C-Enter switches to a multiline equation and these aren't allowed within normal boxes. You need a \parbox here.
In
http://wiki.lyx.org/uploads/LyX/LyXMathebefehle/LyXMathebefehle.pdf
on page 23, you can find an example of a framed labeled box. As I'm shure, that you aren't able to read german, I attached a small lyx-example.
