Hi Michael, I'm just curious if you know about a list somewhere where I can find the number of a specific symbol. What I mean, with your example, is how to find that an arrow corresponds to "\255".
Moreover, Josh wanted the arrow to be really big. Is it possible to make it bigger? I would be interested too!
