I'd like to hear that too. Especially, how to partition a matrix into four quadrants with lines like a big "+" sign? First I created the delimiter brackets for the matrix. Then I made the line by using a Delimiter, with left one invisible and right one a vertical line "|". Then I inserted horizontal lines to both sides of the vertical line with math-fraction. And finally I put a matrix with desired size to each of the quadrants in the matrix. Works, but isn't quite perfect. Specifically, the horizontal line is "cut" by the vertical line. >2.

How do I fix/use the, probably, bug with Multi-line equations when I >mistakely delete the 3rd Square and it becomes only 2? Same problem here. You can press ctrl-enter, which fixes the columns back to the normal three. If you want to delete the last line in a multiline equation, create a new line (ctrl-enter), copy the second-to- last line (which is now third) to the last line, and then delete the two extra lines with ctrl-k. A bit tedious, but works for me. >5. Is there a shortcut to insert delimeters? (opening math panel, >pressing on delim button and apply sure does take lotsa time) Alt-M [ and Alt-M ( does this for square and normal brackets. >7. What's the correct way to insert Hexadecimal digits? (i've been using >m-c r and the letter so it'll be straight) Either that or math text mode, Alt-M M. (skipped a few questions, sorry)
