,----[ C-h f revert-buffer RET ]
| revert-buffer is an interactive compiled Lisp function in `files'.
| (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.
|
| This command also works for special buffers that contain text which
| doesn't come from a file, but reflects some other data base instead:
| for example, Dired buffers and buffer-list buffers. In these cases,
| it reconstructs the buffer contents from the appropriate data base.
|
| When called from Lisp, the first argument is IGNORE-AUTO; only offer
| to revert from the auto-save file when this is nil. Note that the
| sense of this argument is the reverse of the prefix argument, for the
| sake of backward compatibility. IGNORE-AUTO is optional, defaulting
| to nil.
|
| Optional second argument NOCONFIRM means don't ask for confirmation at
| all. (The local variable `revert-without-query', if non-nil, prevents
| confirmation.)
|
| Optional third argument PRESERVE-MODES non-nil means don't alter
| the files modes. Normally we reinitialize them using `normal-mode'.
|
| If the value of `revert-buffer-function' is non-nil, it is called to
| do all the work for this command. Otherwise, the hooks
| `before-revert-hook' and `after-revert-hook' are run at the beginning
| and the end, and if `revert-buffer-insert-file-contents-function' is
| non-nil, it is called instead of rereading visited file contents.

You could have done 'M-x apropos-documentation RET reread'.
apropos-documentation is handy when the command name is not intuitive.
