I haven't found a question post about this exact thing - please link me to one if you do:
Is it possible in LyX to set-up Wrap By Preview for TeX code (written in those TeX code boxes)? I want to set-up something that similar to Instant Preview, only for TeX.
Right now, the only way that I know of to see inside a LyX document the generated is by right-clicking on a TeX box, and clicking on
Wrap by Preview.
I want to automate that with maybe some script that can be written for LyX (or something simpler, if it's possible).
