Company stands for "complete anything". It uses pluggable back-ends and front-ends to retrieve and display completion candidates.
It comes with several back-ends such as
keywords and a few others.
This package is part of GNU ELPA (M-x list-packages).
Advanced users can also download the development snapshot.
Once installed, enable
company-mode with M-x company-mode.
Completion will start automatically after you type a few letters. Use M-n, M-p, <tab> and <return> to complete. Search through the completions with C-s, C-r and C-o.
Type M-x company-complete to initiate completion manually. Bind this command to a key combination of your choice.
When the completion candidates are shown, press <f1> to display the documentation for the selected candidate, or C-w to see its source. Not all back-ends support this.
company-mode in all buffers, add the following
line to your init file:
(add-hook 'after-init-hook 'global-company-mode)
