it wouldnt be bad if there is a tag like CTRL + F for changing the font like CTRL + K or a $font(<text>,<fontname>) identifier for changing that

I think mIRC doesn't support multiple fonts on screen at the same time...

that would be pretty damn annoying
especially with newbie scripters who think the biggest brightest fonts next to tiny fonts are the best looking
its bad enough with the amount of colors out there
