C-y doesn't yank. it pastes.

Wouldn't it be more correct if:

`` yanked to the register and closed the popup
`` inserted into the document and closed the popup
`` pastes into the document and closed the popup - (basically how works today)

Just thinking out loud.

Maybe that can be configured today but I don't see options for insert/paste? Is it possible?

Start by locating the popup keybindings and the current C-y handler, then check whether insert and paste actions are configurable. Done means the proposed C-y, C-i, and C-p behavior is clearly defined and implemented or documented as configurable, with the popup closing after each action.
