Hi,
Which Language setting should be used to paste formulas, i mean here:

Several times I wanted to ask it on old forum engine, but then just selected ‘Javascript’ and postponed it until next time. Here it looks not so good, so maybe I’m just missing a better way to do it?
Well, in my opinion, the Javascript was better in old forum as well, here it’s too much red, while red supposed to be warning/error color. But maybe it’s just a matter of taste and mine is far from perfect.
