Set your own keyboard shortcuts for the Summernote editor on Kanka.
This script is essentially a copy of the default key bindings for Summernote’s keyboard shortcut, and does not change standard behaviour in its released state. You can edit your local copy of the script to bind other key combinations to the functions listed. Keep in mind that those bindings do not supersede those of your browser and/or operating system.
The format should be fairly self-explanatory: change the key code on the left to trigger the option on the right.
