I find, when I write about a a subject, that I need to write the same bits of inline-maths over and over, and I end up copying from earlier in the text, which is tiresome. Having a list on the left, like the 'Most used symbols', containing all the bits of $...$ stuff used in the text would be really handy. Is there a way to get that in texstudio?
\newcommand\fermat{$a^n+b^n=c^n$}
means you just need\fermat
not copying the inline math each time.
