Hi all,

I'm pretty new with how to use HTML text editor effectively when posting the new threads. Generally I can deal with math/physics symbols on the editor bar but don't now how to write that huge square brackets for, say 10x10, matrix and populate it.

I find I have to do a little more:
  • Right-click it
  • Click or move cursor to "Show Math As"
  • Click "TeX Commands"
