Well, you can try the Emacs manual.  In this case, the relevant
part was under (info "(emacs)Files").  You were going about it
the right way.  Another option you could have used might have
been apropos-documentation, which searches in docstrings too.


In this case, I think you want revert-buffer:

/----[ C-h f revert-buffer RET ]
| revert-buffer is an interactive compiled Lisp function in `files'.
| It is bound to <menu-bar> <files> <revert-buffer>.
| (revert-buffer &optional IGNORE-AUTO NOCONFIRM PRESERVE-MODES)
|
| Replace current buffer text with the text of the visited file on disk.
| This undoes all changes since the file was visited or saved.
| With a prefix argument, offer to revert from latest auto-save file, if
| that is more recent than the visited file.
|
| [...]
|
| Optional second argument NOCONFIRM means don't ask for confirmation at
| all.  (The local variable `revert-without-query', if non-nil, prevents
| confirmation.)
