allout-unprefixed-keybindings is a variable defined in `allout.el'.
Its value is

(("[(control ?k)]" allout-kill-line) ("[(meta ?k)]" allout-copy-line-as-kill) ("[(control ?y)]" allout-yank) ("[(meta ?y)]" allout-yank-pop))

Allout-mode functions bound to keys without any added prefix.

This is in contrast to the majority of allout-mode bindings on
`allout-prefixed-bindings', whose bindings are created with a
preceding command key.

Use vector format for the keys:
- put literal keys after a '?' question mark, eg: '?a', '?.'
- enclose control, shift, or meta-modified keys as sequences within
parentheses, with the literal key, as above, preceded by the name(s)
of the modifiers, eg: [(control ?a)]
See the existing keys for examples.

You can customize this variable.

This variable was introduced, or its default value was changed, in version 24.1 of Emacs.
