Properties panel auto select field contents
Mac OS Mojave 10.14.6
Since the Properties panel was introduced in Illustrator, it won't allow selecting an item, then click once on a field name, such as W for the width field, and automatically select the contents of the field so you can then just enter a new value or use the arrow keys to change the value.
It works fine in the Control bar and other panels, just not in Properties.
It works in the Properties panels of InDesign and Photoshop, as well.
Was hoping it would be fixed in Illustrator 2020, but still not.
