Only swear I want… In folder ckeditor-for-wordpress we have a folder plugins. The wpmore is there (!!!). So copy this folder, go to ckeditor/plugins and paste it there. Then in config file write:
config.extraPlugins = 'wpmore'
and the long-awaited key is available.
If somebody know how to do it in right way – write here or write me to email. I’ll be very thankfull.
GoodLuck!
