| Many alternatives: - Like the sibling mentioned, you can use a “compose key” (it’s built in on Linux and can be installed on other platforms). There are other OS-wide options like the TeX input method for Gnome, or TextExpander snippets on Mac. - In Vim, Ctrl-K in insert mode lets you enter “digraphs”. For instance, Ctrl-K *s will insert a Greek letter “sigma”. - In Emacs, C-\ will activate an “input method” such as the “TeX” input method that can insert any math or Greek Unicode symbol using LaTeX notation. (I personally like Emacs’ “transient” input method that is activated for one symbol at a time, since it interferes less with coding.) - In Sublime Text and VSCode there are third-party plugins that insert Unicode symbols via e.g. TeX notation. - Every Julia editor extension, as well as its REPL, lets you press tab to convert a set of LaTeX-like notations into Unicode symbols in a common way. - Most editors have support for snippets of some kind, and many have available snippet packs for common math and Greek symbols. |
