How can I call org-toggle-latex-fragment on all LaTeX fragments in an Org mode doc? I'm coming from Vim, so my instinct is to put something in the init.el that loops through the document and looks for $ and \[ to call org-toggle-latex-fragment on if the file extension is .org. How can I implement this, and is this generally a good approach?

org-toggle-latex-fragment is obsolete since Org 9.3. Use org-latex-preview.
To preview all latex fragments in the buffer pass C-u twice before calling org-latex-preview. Note that a single C-u before org-latex-preview actually removes all previews. For instance, I set the keybinding C-f5 to org-latex-preview then C-u C-f5 removes all previews and C-u C-u C-f5 preview latex fragments on the whole buffer.
Note: org-toggle-latex-fragment has the same behavior, in case you are using an org-mode version before 9.3.

Is it also possible to set `C-f5` to what `C-u C-u org-latex-preview` does directly? If so, how to do it? – student Nov 09 '20 at 20:38

I'm not sure. You can set keybindings to lambda functions and call `org-latex-preview` in a lambda function (or create a named function). The trick part is passing `C-u C-u` programmatically. Maybe [this question](https://emacs.stackexchange.com/questions/21626/how-to-apply-call-interactively-to-an-interactive-command-that-accepts-the-uni) can help. – darcamo Nov 09 '20 at 22:47
