Vim is moving to GitHub
On an unrelated note, why haven't there been any more modal editors?For example, you could enter a "bold formatting" mode, where you could say type "fun" and it results in "𝐟𝐮𝐧". All these are Unicode characters, so you wouldn't need a separate document format like Word.Presumably one can have a "math" mode where you could type math like you would type regular text obviating the dollar signs and backslashes in LaTeX.As I understand it, LaTeX has an incredibly complicated architecture with multiple layers of macros before the lowest layer of TeX primitives. You could replace all that with Unicode symbols.In math mode you could type "in" and get the Unicode symbol "∊". Then you would be able to copy-paste math and send it over email, instant messaging et cetera, and easily type it with a WYSIWYG editor using a traditional keyboard. Of course, there would be numerous problems with typesetting integration limits, fractions et cetera but I think these can be solved using Unicode and clever programming.I currently do not solve say Group Theory problems on my computer because LaTeX is way too inconvenient.I think on a hypothetical editor with a math "mode", one could touch-type math. Maybe I'm missing something and there are insurmountable obstacles to implementing such a solution. If so, I would be happy if someone could point out what they are.Having different modes seems like a very powerful feature, and I'm just surprised the last editor using modes was written 40 years ago.
