Easy way to insert Org options?

Question

I really cannot bear to memorize so many options' name for Org-mode just like learning English vocabulary. For example: #+ATTR_LATEX:, #+tblname:, #+CAPTION for tables, #+ATTR_HTML: for HTML exporting.

In Org-mode, what I've known to do something similar to this are:

1. Block complete: enter <s press TAB to expand to a #+BEGIN_SRC ... #+END_SRC block. (or <e, <q....etc.)
2. Property name complete: C-c C-x p to insert property.

But, is there any built-in function to aid user to input/complete options?

Answer 1

For such in-buffer options, type #+ and then M-TAB gives you a list of completions. This should be bound to pcomplete by default in org-mode. Another standard keybinding provided is C-M-i.

Alternatively, you can set options for a particular export route by using C-c C-e # and tab completing to get the export backend.

The section "Export settings" in the Org Manual describes this reasonably well.
