DIRECT TO where? The clearance was to turn ten degrees and join the final

Any point on the final approach course. One of the 480 "DIRECT" modes
is to set a course to/from an the thing you are going "DIRECT" to.
It's one of the options along with "enter a holding pattern at that

The VTF button is a much cleaner way of doing this.
