That is a standard latex feature called synctex. Pretty much any editor does that.

I believe this functionality is provided by SyncTeX. I'm sure it can be used in other editors, but it can be accessed from the right click menu in TeXstudio.

Latextools through some other means in sublime text can do this as well, both on windows and linux

Quite a few TeX-oriented editors support something like this; a couple that I've used personally are TeXShop (macOS only), TeXworks (cross-platform). Searching for "SyncTeX" suggests that others such as TeXnicCenter and TeXStudio also support it.

I have this set up with vim and evince as well. It's very handy.

Just vim and evince? No synctex as suggested (thanks guys!)

Found a nice SO thread explaining the gist of it: https://tex.stackexchange.com/questions/118489/what-exactly-...

Overleaf and VSCode (with LaTeX workshop) support this.

texworks from a regular miktex install seems to support it via SyncTeX
