BTW [Edward], isn't this documentation, from
https://leo-editor.github.io/leo-editor/customizing.html#simple-settings-nodes,
incorrect - or am I misunderstanding something?
"""
Simple settings nodes have headlines of the form @<type> name = val. These

"""
ISTM that the headlines are of the form
@type val
or can you actually write
@path = <some path>
etc? I can find no examples of this...
