Clicking the mouse on a number on the screen sends the entire number to the host. This is useful on Master Systems which differentiate MLS records by Reference Numbers. Reference numbers start at 1 and increase by 1 to N without repeating from screen to screen. In other words, if a search produces 47 matches, the host will display them over several screens, and the numbers from 1 to 47 will uniquely identify each one. You may exploit this feature as follows:
1. View each screen full of matches, right-clicking on the ones that interest you.
2. When you finish with that screen, tell the host to queue those numbers (rather than viewing the full listing information right away).
3. After the last screen, view all the numbers you have collected.
Note: you may also tag MLS numbers by holding down the Ctrl key as you left-click them.
