Describe the feature

It doesn't seem possible to do vim word completion in Zed. In regular vim, it's ctrl-p/ctrl-n, but in Zed that goes to previous line/next line.

For example, if I type the following, then hit ctrl-p after typing autoc, vim mode should complete the word to autocomplete:

This document contains the word autocomplete.
Let’s try to autoc<ctrl-p>

Expected result:

This document contains the word autocomplete.
Let’s try to autocomplete

VIM autocomplete has a lot of features that would be useful in Zed. The docs include some useful options:

The Vim editor goes through a lot of effort to find words to complete. By default, it searches the following places:

1. Current file
2. Files in other windows
3. Other loaded files (hidden buffers)
4. Files which are not loaded (inactive buffers)
5. Tag files
6. All files #included by the current file

…

If you know what you are looking for, you can use these commands to complete with a certain type of item:

CTRL-X CTRL-F file names
CTRL-X CTRL-L whole lines
CTRL-X CTRL-D macro definitions (also in included files)
CTRL-X CTRL-I current and included files
CTRL-X CTRL-K words from a dictionary
CTRL-X CTRL-T words from a thesaurus
CTRL-X CTRL-] tags
CTRL-X CTRL-V Vim command line
