CTRL-X CTRL-F           On Windows, when completing paths that only consist of
                        forward slashes, temporarily set 'shellslash' so that
                        the completion candidates use forward slashes instead
                        of the default backslashes, too.

Fix the multi-line completion problem.

CTRL-G CTRL-P           Show extra information about the currently selected
                        completion in the preview window (if available). You
                        need to re-enable this for each completion.

<Enter>                 Accept the currently selected match and stop completion.
                        Alias for i_CTRL-Y.
                        Another <Tab> will continue completion with the next
                        word instead of restarting the completion; if you
                        don't want this, use i_CTRL-Y instead.

                        Quick access accelerators for the popup menu:
1-5                     In the popup menu: Accept the first, second, ...
                        visible offered match and stop completion.
9-6                     In the popup menu: Accept the last, second-from-last,
                        ... visible offered match and stop completion.
                        These assume a freshly opened popup menu where no
                        selection (via <Up>/<Down>/...) has yet been made. In
                        a backward completion (first candidate at bottom), the
                        counting starts from the bottom, too; i.e. 9 is the
                        candidate displayed at the top of the completion
                        popup.
<S-CR>                  In the popup menu: Accept the second visible offered
                        match and stop completion; shortcut for 2 that may be
                        quicker to reach.

Aliases for popupmenu-keys:
CTRL-F                  Use a match several entries further. This doesn't work
                        in filename completion, where CTRL-F goes to the next
                        matching filename.
CTRL-B                  Use a match several entries back.

<Esc>                   Abort completion, go back to what was typed.
                        In contrast to i_CTRL-E, this also erases the
                        longest common string.

CTRL-N / CTRL-P         Inline completion without popup menu:
                        Find next/previous match for words that start with the
                        keyword in front of the cursor, looking in places
                        specified with the 'complete' option.
                        The first match is inserted fully, key repeats will
                        step through the completion matches without showing a
                        menu.
                        One can abort the completion and return to what was
                        inserted beforehand via <C-E>, or accept the currently
                        selected match and stop completion with <C-Y>.
                        It is not possible to abort via <Esc>, because that
                        would clash with stopping insertion at all; i.e. it
                        would then not be possible to exit insert mode after
                        an inline completion without typing and removing an
                        additional character.

On completion with multiple matches, insert the longest common text AND
pre-select (but not yet insert) the first match. When 'completeopt' contains
"longest", only the longest common text of the matches is inserted. I want to
combine this with automatic selection of the first match so that I can both
type more characters to narrow down the matches, or simply press <Enter> to
accept the first match or press CTRL-N to use the next match.

Shorten some commonly used insert completions.
CTRL-F                  File name completion i_CTRL-X_CTRL-F

CTRL-Space              IDE-like generic completion (via the last-used omni
                        completion ('omnifunc'). Also cycles through matches
                        when the completion popup is visible.

CTRL-X [N] CTRL-D       Limit 'dictionary' to the [N]'th entry for this
