# *mark up editor mode*

How do i find the command to view lyx in the mark up editor mode, where on can add command to insert new packages layouts, margin spaces, centering etc, and the document class such as . For example

See this question as an example. Is there a way to fix the limitation of cleveref package regarding citation of subfloats?

It has not so much to with that particular question, this is just an example of what I am asking about. If you look at that question and you and scroll down to the picture of a 'screen shot of a big greyed section of a lyx document', its listed as being created by source code.

THis is what I am asking about. How do do this or view my lyx document in that form. Greyed out add command, use package form.?

\sloppy


use[package]..

I will give a better example soon
