Oh - seems like the alt key needs to be pressed + held? I missed that the first time... 😛 Then I kept mousing over before pressing "alt", only for nothing to happen. Finally figured out after 5m to hold alt first. (Esp since I wasn't sure which of my macbook keys even were "alt", due to rebindings and my option key not saying "alt" on it.)
first idea: add title to the links, but that may not be great if they already have a title.
Another idea is to have a second [[Tippy]]. That's running on long delay and will tell you that you have to press a button to get actual preview
(preferred) A variation on that - have a tooltip that would show up first 5 or so times you hover over links and then never again (store in browser storage)
