You can indent the region, to do this for the whole buffer: mark whole buffer with C-x h (or M-x mark-whole-buffer) run indent region with C-M-\ (or M-x indent-region)

Perhaps your confusion arises from not having used an actual terminal. Back when serious computers were the size of several upright refrigerators, a terminal communicated with a central computer over a serial cable using characters and characters only. The characters were part of some standardized character set, e.g. ASCII or EBCDIC, but typically ASCII. ...

This is non-standard terminology, and the distinctions apply specifically when running Emacs under X11. “Emacs copy/paste” are the Emacs commands that access the kill ring. They are Emacs commands; depending on how Emacs is configured, they may only affect Emacs internally, or they may also interact with the X11 selections. “X copy/paste” are operations on ...

Terminals transmit characters (more precisely: bytes), not keys. When you press a key or a keychord like Ctrl+;, this information has to be encoded into a sequence of bytes. Keychords that represent a character, like A or Shift+A or À, are sent as that character: a, A, à (the last one being one or two bytes depending on the terminal's character encoding). ...

This is not possible, because the validity ranges of different encodings do overlap, thus one cannot unequivocally determine which chunk of text has which encoding. You might not like the answer, but these are the facts, in my opinion.

Works for me. Try placing your cursor inside the equation and hit C-c C-x C-l. This is the default shortcut for org-preview-latex-fragment. C-c C-x C-l will generate the preview and C-c C-c will revert to your original code. You can also type M-x org-preview-latex-fragment. And if you ever forget, just hit the [TAB] key anytime after hitting M-x to get a ...
