Ctrl-N: Words You Already Wrote
The keystroke
In insert mode, type the first few letters of something that already exists in the file and press Ctrl-n.
A real popup menu appears listing every matching word in the buffer, and the status line reads:
-- Keyword completion (^N^P) match 1 of 3No plugin. No language server. Nothing installed.
Moving in the menu
| Key | Does |
|---|---|
Ctrl-n | next match |
Ctrl-p | previous match |
Ctrl-y | accept — y for yes |
Ctrl-e | cancel, and give back exactly what you typed |
Why it earns its place
Every long identifier you have already typed is available as a completion for the rest of the session, for free. In a file full of handle_create and get_by_priority, that is most of your typing gone.
