To perform a Select All in 4D Write Pro, the function is reliant on the selectAll standard action using the constant ak select all. This function is provided in the default Edit menu but is not included with the 4D Write Pro toolbar or contextual menu.

When performing a select all in 4D Write Pro, only the content of the currently active section (header, body, footer) is selected. This is the same behavior that is seen in other word processors.
