Can't draw a flow chart on here, so I'll try to verbalise it ...
Did defender intentionally play ball to keeper. If YES then carry on below, if NO then walk right away and leave them to it (even if the ball accidentally ends up at the keeper).
If above was YES, does keeper handle the ball? If NO then nothing to see here, if YES then it is an indirect free kick.
Honestly, some of the posts on here make it sound like rocket science, it isn't. Refereeing is complicated enough, don't make it more complicated than it needs to be.
