excel - What does mean the colon with equal sign ":="

Question

If foud this code:

ActiveCell.Offset(-5, -1).Range("A1:E1").Cut Destination:=ActiveCell.Range( _
        "A1:E1")

I can't find any reference about ":=". What does it mean?

Answer 1

:= is used with named arguments. In this case, Destination is the name of an argument to the Cut method, and the other side is its value.

See https://docs.microsoft.com/en-us/office/vba/language/concepts/getting-started/understanding-named-arguments-and-optional-arguments for an example.
