I sometimes work on LaTeX files in VS Code in tandem with the LaTeX Workshop plugin. The plugin has a snippet feature to help with some common LaTeX commands and symbols.
Interestingly, it has a symbol picker (snippet view) tab that allows finding symbols either by search or eyeballing, and inserts the LaTeX command for the symbol right in the editor:
It would be awesome if a similar thing was implemented as an Obsidian plugin that would spare me googling for the commands like “TeX equal sign with two dots” or drawing a symbol poorly with my mouse on detexify .
