By default, your Planner pages will have a Notes section. You can put
anything you want in this section, or remove it from your
planner-day-page-template entirely.
You may be interested in remember-planner.el, part of the Remember package (see see remember-el). You can download Remember at http://gna.org/projects/remember-el/).
remember-planner.el makes it easy to create notes from anywhere
in Emacs, and it uses the same context-sensing code that Planner uses.
Notes added by remember-planner.el look like this:
.#1 Headline 00:00
Body
[[context hyperlink]]
and are outlined at the H2 level in published HTML.
You can easily create context-aware notes if you include the following in your ~/.emacs:
(require 'remember-planner)
(setq remember-handler-functions '(remember-planner-append))
(setq remember-annotation-functions planner-annotation-functions)
Then M-x remember will open a dedicated buffer for you to write your note. If Planner recognizes your current buffer as one with context then it will include a hyperlink at the bottom of the note. The first line of the note is used as a title, so make it short and meaningful. The rest of the text will be used as the body. Try it now by creating a note, perhaps about things you'd like to remember from this tutorial.
Typing C-c C-c after composing will prompt for a plan page to put the note on, with auto-completion. If you don't enter a page, the note will just be saved on today's page. If you do specify a plan page, the note will go on both today's page and on the specified page. Let's try specifying ‘TaskPool’ for the note.
If you look at today's page, you'll find a timestamped note that links to ‘TaskPool’. Likewise, ‘TaskPool’ contains a note that links to today's page. To change the plan page of a note, use planner-replan-note.
If you decide to edit the note on one of these pages after it has been saved, be aware that your changes will not be automatically reflected on the linked page. To update the linked page after editing a note, use M-x planner-update-note.
