Macro for opening lower zone in its own window

I want to be able to assign a key command for a separate window to open from the lower zone. In the upper right of the lower zone it seems to indicate on the arrow icon that the macro is <!> that dosen’t work for me and I don’t know how to alter it because I don’t know what it is called in the key command list. Anyone know?

Don’t know the answer. But if you are in the Key Commands and use the Search Box to look for “lower” or “zone” it would take maybe a couple of minutes to either find the Command or verify it doesn’t exist.
