Julia mode for Emacs, Vim, and VSCode lets you to use LaTeX-like sequences: write \pm, press <TAB>, and you get ± Of course, this only works if your editor supports this and you are using a language similar to Julia. But there are two more general methods that are applicable everywhere. The first was mentioned by db48x: I have customized my Xmodmap file so that greek letters and a few typographic characters I use often can be typed using AltGr combinations. (Unfortunately, this is much more complicated if you use Windows.) Secondly, I heavily use Espanso [1], so that I can easily type complicated letters/sequences (e.g., my email address) for which it would be too overkill to assign an AltGr keybinding. Finally, in Emacs and Kitty (my terminal emulator) there is a keybinding that asks for the name of an Unicode symbol and enters it. (In Emacs it's C-x 8 <Enter>, in Kitty Shift+Ctrl+u.) From the point of view of my workflow, the problem of quickly typing Unicode characters is completely solved. [1] https://espanso.org/ https://espanso.org/
