Data Tooltips

Data Tooltips show you summary information about selected features. By holding down the Option key while moving over any item in the selected layer, a small window will appear with information about the item you have moved over. The information that appears is defined in the Layer Info window.

Further, if you prefer to have Data Tool Tips available at all times without having to hold the option key, you can toggle them by choosing  Map > Show Data Tooltips
