;;; Commentary:
|

|
||||
;; nov.el provides a major mode for reading EPUB documents.
|
||||
;;
|
||||
;; Features:
|
||||
;;
|
||||
;; - Basic navigation (jump to TOC, previous/next chapter)
|
||||
;; - Remembering and restoring the last read position
|
||||
;; - Jump to next chapter when scrolling beyond end
|
||||
;; - Storing and following Org links to EPUB files
|
||||
;; - Renders EPUB2 (.ncx) and EPUB3 (<nav>) TOCs
|
||||
;; - Hyperlinks to internal and external targets
|
||||
;; - Supports textual and image documents
|
||||
;; - Info-style history navigation
|
||||
;; - View source of document files
|
||||
;; - Metadata display
|
||||
;; - Image rescaling

Start `org-noter' session.
|
||||
|
||||
There are two modes of operation. You may create the session from:
|
||||
- The Org notes file
|
||||
- The document to be annotated (PDF, EPUB, ...)
|
||||
|
||||
- Creating the session from notes file -----------------------------------------
|
||||
This will open a session for taking your notes, with indirect
|
||||
buffers to the document and the notes side by side. Your current
|
||||
window configuration won't be changed, because this opens in a
|
||||
new frame.
|
||||
|
||||
You only need to run this command inside a heading (which will
|
||||
hold the notes for this document). If no document path property is found,
|
||||
this command will ask you for the target file.
|
||||
|
||||
With a prefix universal argument ARG, only check for the property
|
||||
in the current heading, don't inherit from parents.
|
||||
|
||||
With 2 prefix universal arguments ARG, ask for a new document,
|
||||
even if the current heading annotates one.
|
||||
|
||||
With a prefix number ARG:
|
||||
- Greater than 0: Open the document like `find-file'
|
||||
- Equal to 0: Create session with `org-noter-always-create-frame' toggled
|
||||
- Less than 0: Open the folder containing the document
|
||||
|
||||
- Creating the session from the document ---------------------------------------
|
||||
This will try to find a notes file in any of the parent folders.
|
||||
The names it will search for are defined in `org-noter-default-notes-file-names'.
|
||||
It will also try to find a notes file with the same name as the
|
||||
document, giving it the maximum priority.
|
||||
|
||||
When it doesn't find anything, it will interactively ask you what
|
||||
you want it to do. The target notes file must be in a parent
|
||||
folder (direct or otherwise) of the document.
|
||||
|
||||
You may pass a prefix ARG in order to make it let you choose the
|
||||
notes file, even if it finds one.
