Comment 4 for bug 409358

I wish I were less dense - I don't understand how to turn off this. I asked on Emacs Devel since there seem to be some old left over info in the CC Mode manual.

You can however turn it off by changing the keymap c-mode-basemap where c-electric-paren is bound. (At least I believe so, I did not test right now.)

Keymaps can inherit from other keymaps. I think C-h b (which calls describe-bindings) should show helpful information in cases where bindings are inheritied.
