I think it'd be nice to have one or two buttons on examples that have other quick paste codes.
So if you had the example "$bp(muted, mi(cover))$" it could have a "muted" button so you could just easily hit "muted" which would paste "muted" where your cursor is like it does the full example.
I know I could just type "muted" but there's a lot of times where I will constantly flip through an arguments in a formula to find what looks good which taking away typing and able to replace the single argument would be nice.
As well as long pressing isn't an option because if you're using the second argument as a global variable, you'd constantly have to retype that as well.
I can make an example on stackblitz later when I'm home.
