Dear list, After some more thoughts, I plan to implement this feature like the following. Comments are welcome.
1. An on/off menu under "view" called "view latex for selected text" or simply "view latex". It will be enabled with a valid latex document . Support for docbook etc may be pending. 2. When a piece of code is selected, a window is displayed with the latex code of the selected paragraphs. This window will be updated with the next selection event, and close when "view" -> 'view latex' is turned off. Rationals: 1. This will be a great feature to learn latex, 2. This will make debugging of latex-related errors much easier. For example, today, I copy/paste a *centered* figure into a table and get a latex error. Only after I look up the latex export did I find out the problem. 3. view-latex will be a more frequent event than view->pdf etc so I do not want to call an external viewer. 4. It is tempting to update latex code at each key stroke but that will be too expensive. Select event seems to be a better choice. Cheers, Bo
