Is it possible to add a text box that appears when you hover over a word in the text? Think wikipedia-style, but that we can use internally (especially helpful in onboarding) to quickly explain terms, acronyms, etc.
Dear @Leea,
With the “@” and a 2 column table you can make some basic explanation.
When you hover over the word 
it will show a small text box as in the picture shown.
when you click on it, it will show a bigger frame that you will be able to amend to your needs under 1 and 2
I would advise to play with it 
Another option is to use this JSON trick to create an untyped object that shows the first field as its display value and more fields on hover:
Taken from this doc here:
P.S. You can use spaces as keys of that JSON to make a more compact tooltip:
@Jean_Pierre_Traets 's approach above is overall simpler though. A table is easier to edit than a formula and unlike a formula it won’t calculate towards object quota in a free plan. My solution is more of an alternative for one-offs where you’d want this minimal tooltip UI specifically.
