I am new to VIM and I had this happened on few occasions. I am using these plug-ins:
- nerdcommenter-master
- vim-autoclose-master
- vim-multiple-cursors-master
- nerdtree-master
- vim-autocomplpop
Sometimes I am typing python commands and autocomplete comes up, and I accidentally hit something. This new tab pop-ups with help text, describing the autocompleted command, basically like using pydoc. I'd like to know what this is called and how can I invoke it (I find it very useful).
What you see is the omni completion from the Python filetype plugin that ships with Vim, in
$VIMRUNTIME/autoload/pythoncomplete.vim. It is automatically triggered by the AutoComplPop plugin. You can also explicitly invoke it by pressing<C-x><C-o>in insert mode;:help i_CTRL-X_CTRL-O.The preview comes courtesy of
:set completeopt+=preview.
