+Besides math there are other cases where you might like to see a preview,
+ fox example things that LyX cannot render like rotated parts or things
+ which are not yet supported by LyX.
+ To do this, insert a preview inset via the menu 
+\family sans
+Insert\SpecialChar \menuseparator
+Preview
+\family default
+.
+ Insert or paste the stuff that you want to preview into this inset.
+ The preview will be generated when the cursor is outside the preview inset.
+ If you click on the preview, you can edit the previewed stuff.

+An example: To create rotated boxes, you use the LaTeX command

+\backslash
+rotatebox

+ Instead of the TeX Code boxes you want to see in LyX the final rotated
+ boxes, for example to adjust the rotation angle to fit with the surrounding
+ text.
+ Therefore you create a preview inset and copy the text with the rotated
+ boxes into in.
+ Here is the result:

+If LyX does not show a preview, assure that you enabled previews as described
+ above and also assure that TeX Code in the preview inset is valid and that
+ you loaded the LaTeX packages in your document preamble that are required
+ by the TeX Code.
+ If LyX cannot create a preview, you will in most cases also not be able
+ to view your document due to LaTeX errors.
+ So if you have to use some TeX Code and don't know if it is correct, the
+ preview inset is a nice method to check it without the need to view the
+ whole document.
