Copying text with Ctrl + C when the Zsh line editor is active

I've added some keyboard shortcuts in my Zsh to enable selecting words. In order for the selection to do something, I would like to use Ctrl + C to copy it. However I would also like to use Ctrl + C to interrupt programs, when the Zsh Line Editor (ZLE) isn't active. Is this possible and how can I do this? I tried to declare a function TRAPINT to hook Ctrl + C, however when I'm in the ZLE and hit Ctrl + C, this function doesn't appear to be called.
