As I am using the discussion board to write posts for a while, I think it is really a powerful platform to communicate with fellow coders in exchange of ideas and sharing code.
However, as conversion going deeper and deeper, more often than before I feel it is inconvenient to write common math symbols (subscript, superscript, etc) and Greek letters manually via html code every time. I notice that Leetcode discussion forum is powered by Markdown with some commonly used formatting built-in as handy buttons above the editing area. I am wondering whether Leetcode could add more shortcut buttons for frequently used math symbols as well? I understand that using math symbols/formatting in posts might not be common in coding problem discussions, but they indeed help a lot in some complex problem analysis.
Some examples: subscript xk, superscript xk, Sigma Σ, sigma σ, etc.
