MatTalX - Write math symbols

This is a very handy extension! As an engineering professor I often need to use dashes, super/subscripts and Greek letters in Gmail and course websites. Previously, my only option was to copy these symbols from elsewhere (e.g., Word or Windows Character Map), but this was very clunky. With this extension, I find myself saving a lot of time. For those trying to insert an em dash, \emdash works. There seems to be no equivalent for the en dash.

Very useful and handy!

Really useful!
