Tooltip as a hidden internal block or link

Hi,

I would like to insert text as tooltip or popup just as markdown code in the context.
The tooltip would be hidden in the row or in a block but popup over the linked text.
Is there any suggestion or can you implement it in the Obsidian if doesn’t exist!
It works really just like the case of the external link.

You can use <abbr title="Your ingenious tooltip here">Ordinary text</abbr>, and it’ll give you the tooltip in both live preview and reading mode.

I found this, when wanting to have short titles in tables, but alas since they’re so lengthy, the advanced table plugin expands the column to match the full definition, so I’m having to resort to footnotes.

So now I’m looking for how view footnotes as tooltips. Not sure if it’s possible, or not.

Thanks
