remember: Quick Start
4 Quick Start
*************
• Type ‘M-x remember’. The ‘*Remember*’ buffer should be displayed.
• Type in what you want to remember. The first line will be treated
as the headline, and the rest of the buffer will contain the body
of the note.
• Type ‘C-c C-c’ (‘remember-finalize’) to save the note and close the
‘*Remember*’ buffer.
By default, ‘remember-finalize’ saves the note in ‘~/emacs.d/notes’.
You can edit it now to see the remembered and timestamped note. You can
edit this file however you want. New entries will always be added to
the end.
To remember a region of text, use the universal prefix. ‘C-u M-x
remember’ displays a ‘*Remember*’ buffer with the region as the initial
contents.
As a simple beginning, you can start by using the Text File backend,
keeping your ‘~/.emacs.d/notes’ file in outline-mode format, with a
final entry called ‘* Raw data’. Remembered data will be added to the
end of the file. Every so often, you can move the data that gets
appended there into other files, or reorganize your document.
You can also store remembered data in other backends. 
Backends.
Here is one way to map the remember functions in your init file
(The Emacs Initialization File (emacs)Init File.) to very
accessible keystrokes facilities using the mode:
(define-key global-map (kbd "<f9> r") 'remember)
(define-key global-map (kbd "<f9> R") 'remember-region)
By default, remember uses the first annotation returned by
‘remember-annotation-functions’. To include all of the annotations, set
‘remember-run-all-annotation-functions-flag’ to a non-‘nil’ value.
-- User Option: remember-run-all-annotation-functions-flag
Non-‘nil’ means use all annotations returned by
‘remember-annotation-functions’.
You can write custom functions that use a different set of
remember-annotation-functions. For example:
(defun my/remember-with-filename ()
"Always use the filename."
(interactive)
(let ((remember-annotation-functions '(buffer-file-name)))
(call-interactively 'remember)))
The ‘remember-notes’ command creates a “notes” buffer that visits the
file specified by the option ‘remember-data-file’. The option
‘remember-notes-buffer-name’ specifies the name of the buffer. The
buffer uses ‘remember-notes-initial-major-mode’ and
‘remember-notes-mode’ minor mode. Use ‘C-c C-c’ to save and bury the
buffer. The command ‘save-some-buffers’ saves this buffer without
asking. This function is a suitable setting for
‘initial-buffer-choice’.
