I find it interesting that I can use a computer program like RootsMagic for a long time and still occasionally find features that prove very useful. Two such features are the Command Palette and under that the Count Trees.
Somewhere I saw a reference to a Command Palette so I began looking for it. Viola, there it was in the upper right part of the screen. Wow, what a easy to access a lot of useful commands, including some commands I was not aware of.
One such command is Count Trees. I use that command to identify unconnected and duplicate individuals.
