Re: Footnote tooltips (an attempt)

["Juan Manuel Macías" <maciaschain@posteo.net>]

I answer myself to comment a couple more things on this question of
footnotes and tooltips. I think my approach is quite poor, and also when
it comes to files with many notes, it takes a long time to create or
update the list of tooltips. So I think I'll give up on' footnote
tooltips. If what it is about is being able to see the content of a
footnote quickly, I have written this other simpler function, which
displays the content of a footnote at point, in the echo area. Since
`<C-h .>' (`display-local-help') is not very useful in a footnote
reference, I recycle the shortcut for my function, if the context is a
footnote reference. I share it here, in case it is useful to someone.
