* org mode

To open the org manual using "meta" within emacs:

: M-x org-info

Optionally you can use the following keybinding to open a buffer with the info
version of manuals:

: C-h i

Then, in the buffer type the key "m" to search in the menu by keywords. To find
the org info manual, just type "Org mode" in the menu. 

** Create task list and include date and time

Save a ".org" file. Then write your tasks using "*" to show hierarchy or nesting
structure in tasks.

** Using Pomodoro in org mode

- Install pomodoro in emacs

: M-x [RET] package-install org-pomodoro

- Initialize a clock in a task

: M-x [RET] org-clock-in

- Initialize pomodoro

: M-x [RET] org-pomodoro

PS: "RET" is the same "enter" key

** org-babel

Reference for header arguments:

https://org-babel.readthedocs.io/en/latest/header-args/

** Org babel does not embedd R plot

org version 9.3

https://orgmode.org/Changes_old.html

:file header argument no longer assume "file" :results

The "file" :results value is now mandatory for a code block returning a link to a file.
The :file or :file-ext header arguments no longer imply a "file" result is expected.

** Include templates in org babel

Use:

: M-x org-insert-structure-template

Or keybinding

: C-c C,

Then choose an option (src, example, center, comment)

Or use org-tempo. To include a src code block in the document:

: <s TAB

Change the letter for each option that you need (a, C, c, E, e... for "export ascii",
"comment", "example"...)
