Introduction
LaTeX IME in ibus-table is using the commands in LaTeX to input lots of symbols. I think this is useful, because I familar some commands in LaTeX for input mathematic symbols. E.g. in LaTeX, we use \sigma to input σ and \Omega to input Ω. Obviously, we only use ascii to represent symbols, and this handy methods can make our symbol inputs easy :)
Remenber, we only input symbols not mathemathcal expression pictures.
What we can input and how
Here is the key stroks and inputted symbols, I know, it is a bit long :)
