MapTips in ArcMap is a very handy feature and it doesn't seem to exist in ArcGIS Pro. Please consider adding this feature.
Is this what you are looking for? If so, then it is implemented in Pro 2.0.
Hi George. Just saw your comment. No, that is not the equivalent to MapTips. As Bill mentions below, MapTips allows you to hover over a feature in one of your layers and get a small pop-up showing an attribute from a field of your choosing. This is handy when you don't want to display all the labels for a layer but want to see one on the fly.
I agree this is a very useful feature. Being able to just hover over features and find what you want is very useful. please add this to ArcPro.
We'll see this in the Pro 2.2 release coming this summer.
You can now add map tips for layers in ArcGIS Pro 2.2.
