How to accept a suggestion from Vim YouCompleteMe plugin

Question

When there are multiple complete suggestions from Vim plugin YouCompleteMe, how do I accept the one I want ?

What I currently do is pressing Esc key, I just want to know if I got it right.

Answer 1

To accept the current insert completion entry use <c-y>. Think of it as "yes".

For more help see:

:h complete_ctrl-y

Answer 2

Usually with Ctrl + Y (yes); read up :help popupmenu-keys.

Answer 3

Ctrl-Y is default, but you can add other key bindings by adding this line to your .vimrc:

let g:ycm_key_list_stop_completion = ['<C-y>', '<CR>']

In this ^ example, you can use either Ctrl-Y or Enter to accept the completion and free up the cursor.
