 #### Toolbar icons
 
-Below are the built-in toolbar icons (only some of which are enabled by default), which can be reorganized however you like. "Name" is the name of the icon, referenced in the JS. "Action" is either a function or a URL to open. "Class" is the class given to the icon. "Tooltip" is the small tooltip that appears via the `title=""` attribute. Note that shortcut hints are added automatically and reflect the specified "action" if it has a keybind assigned to it (ie. with the value of "action" set to `bold` and that of "tootip" set to "Bold", the final text the user will see - assuming the default shortcuts are unchanged - would be "Bold (Ctrl-B)").

 Additionally, you can add a separator between any icons by adding `"|"` to the toolbar array.
