The Ctrl-X Sub-Completions

Specialized completion: filenames, lines, dictionary, omni.

Keys: Ctrl-X

Ctrl-X enters a sub-mode where the next key picks a completion source: Ctrl-F for filenames, Ctrl-L for whole lines, Ctrl-K for dictionary, Ctrl-O for omni-complete (language-aware), and more.

The Ctrl-X Sub-Completions

Plain Ctrl-N pulls from buffers. The Ctrl-X prefix opens a sub-menu where the next key chooses a more specific source.
