['<C-y>'] = cmp.config.disable not required?

[flaphoschi]

Hello!
The recommended configuration contains this line:

['<C-y>'] = cmp.config.disable, -- Specifycmp.config.disableif you want to remove the defaultmapping.

I assumed this disable configuratin shown in default.lua. But whether it use that line or not C-y duplicates the characters from the line above.

• My impression is that default.lua is not the default configuration loaded e.g. the tab key doesn't work
• If a user preferes the default behavior of Neovim for C-y the configuration from above is not needed

Correct?
Thank you
