First, is there any keyboard-shortcut way of inserting a matrix in a math formula (I usually prefer keyboard shortcuts to having to go to the math panel).
Also, what is the status with the various math symbols that show up as LaTeX text rather than their symbol in LyX. (e.g. \emptyset shows up as red "emptyset" rather than the actual symbol). I'm using LyX 1.2.1. Is my setup wrong? (This only happens for some symbols, so I'm assuming my setup is fine). Since all the symbols are in the math panel it seems you've already got the pixmaps/characters for them so is there anything I can do to make them also show up in my formulas? Please email responses as I'm not subscribed to the mailing list... Thanks.
