It's more comfortable writing my questions in LyX then copying the text as MathJax code and post it in MathExchange. the problem is that every time I need to do this copy and paste I need to delete certain things like brackets and so on.
I have seen a similar question on Tex but there was no real solution for the problem: Lyx: exporting document in a "MathJax compatible" way
is there any new way to solve this problem?
