" 1. Edit the variables below (or override in .vimrc)

|
|
" 2. copy this file into .vim/plugin/
|

|
|
" 3. - now in insert mode do 'C-x C-o' to autocomplete the thing at the cursor
|
||
|
|
" - in normal mode do 'gd' to go to definition
|
||
|
|
" - 'gD' goes to the definition in a new vertical split
|

|
|
"

|

" (This plugin is best used with the 'hidden' option enabled so that switching buffers doesn't force you to save)
