Explorer goes into rename mode if a selected item is clicked again outside of the 'double click to launch' period. It doesn't matter how much the mouse is moved, or how much time passes. This behaviour (right or wrong) is used in File Explorer, XYPlorer, Tablucus, Q-dir, Direttore, etc.
Having to keep the mouse in position and then not knowing how long a 'time window' to wait before the 2nd click works (or overshoots and doesn't work any longer) seems less intuitive. I feel like if I click too quickly I end up running an app, or too slowly and I have to start over.
