Problem arises if I made a mistake and then need to edit. Then selecting and modifying via the gui is tedious and I usually wind up erasing accidentally large parts, and basically starting over. This is where editing the underlying TeX would save trouble.

Use a TeX inset > rather than a math one, and it will work. Another way to scratch your (La)TeX itch is to use LyX's layouts. You can make your own environments and insets and you define the LaTeX that is behind all of those. For my use, I've found that if there's a customization that I just want once, ERT is great. If I find myself doing something many times, I am starting to consider making a module or adding to my local layout. See the customization manual for information on these options. Scott

I do understand this tendency, since I also came to LyX with a TeX background. Way back when LyX was young, Matthais set up the math-insets the way you would want them, and math was just written in what we now call ERT (Evil Red Text, a TeX inset. It's evil mostly because you have the usual problems that if your code is wrong, it won't produce any output and TeX will yell at you.). You can still do that if you want. Use a TeX inset rather than a math one, and it will work. I always just write the TeX out (e.g, \alpha) inside the math inset, and it now is instantly changed to display correctly, which I still think is cool. If it doesn't change to a real display of the symbol, I know I made a mistake. Better than a spellchecker. There are some things I hate to set up in TeX, like tables, matrices. Then, I use the menus. For me this is the best of both worlds. If there is a way to display the raw TeX of a math inset, I suppose it would be useful in some circumstances. Maybe someone will point out how to do that, and then you can set that up to be automatic, maybe. Or you can just use ERT.

HTH, if anyone is so kind to translate this and upload to the wiki please be welcome I might be able to take a crack at that, but not until after mid-April.

Re: editing math in lyx
I would really love to be able to conveniently edit the TeX code directly - I'd be vastly more productive. I find lyx gui editing - as all other math editors - to be terribly frustrating and unproductive. I used LaTeX since 1980s, and the lack of this is the only thing that makes me think twice before deciding to use LyX instead of just using LaTeX. OOps, sorry wrong thread! You can edit directly the TeX code by selecting the equation inside math mode (ctrl+C) and paste outside math mode (ctrl+V) then you will have the TeX code directly (you can also place TeX code directly without to enter math mode). When you finished select again your Tex code and press Ctrl+M. Voilá. HTH Alex

The solution I prefer is then manually select your equation inside math mode, cut and paste outside math mode (it will be displayed as TeX code). These can be automated by the shortcut: command-sequence char-forward; line-end-select ; cut; char-backward; paste; char-delete-forward. hen you finish to edit select the whole code and press ctrl+m. Voilá, Everything goes as expected. So thankyou very much Scott for pointing me in the right direction. Alex

Re: editing math in lyx
1. Position the cursor just inside the numerator (you should see 'Font: textrm' in the status line). 2. Hit backspace (removing the font selection and reverting the numerator to normal math font). 3. Select the contents of the numerator. 4. Type '\textsf' and hit the space bar. It will appear to be overwriting the numerator, but when you hit the space bar the numerator contents will be there, in the new font. 5. Repeat for the denominator. Paul
