How do you type <C-x><C-o> in Vim?

Question

What keys do <C-x><C-o> represent in Vim? My goal is to get autocompletions working for Golang.

I've installed this plugin and have the syntax highlighting working.

https://github.com/fatih/vim-go

The readme says that, "Autocompletion is enabled by default via <C-x><C-o>", but I don't know which keys to press.

Answer 1

It's Ctrl+X, Ctrl+O. This combination is used in Vim for omnicompletion. Type :h omnifunc or :h ft-go-omni (I presume) for more information.

Answer 2

• go is executable?

  do you add path to golang into $PATH?

• vim-go is loaded?

  if you are using vim-plug or pluggable interface for plugins, you should have vim-go in ~/.vim/bundle

• are you editing go file?

  check :set ft? is go
