Okay, so I have a collection of mice that are new but the model is old. I also have students who are not able to differentiate between left-clicking and right-clicking. These mice cannot be programmed in the computer’s system preferences, and the companies no longer have the drivers on their Web sites. My solution? I folded up a small piece of paper towel and very carefully inserted it in the edge to prevent the right button from clicking. I had to try a few different placements to make sure that the button was disabled without the paper towel activating the click internally (so that the right button acts as if it is always down). I needed two small paper towel pieces for another mouse, one on the right edge and one on the back edge (near the user’s wrist). Ideally, I could just program both buttons to left-click, but this is a cheap alternative when programming is not available.
Some people remove the paper, but so far I have remained calm. Some of my students pull out the paper, but it is easy to replace, so I don’t worry. If I make a big deal out of telling the students to leave the paper alone, I can guarantee that it will be removed more often. Some staff members have pulled out the paper, possible so that they can right-click themselves or because they think a student put it there. Again, I just replace the paper. I think that most of the teaching assistants and therapists who use the computers have finally gotten used to my low-tech adaptation. Many students love playing with paper and string, so I expect that the paper will always be occasionally removed. I would rather have the students play with the paper than with the mouse or headphone wires.
This method does not teach students to avoid the right mouse button, but it does prevent students from accidentally right-clicking on everything. Many of my students are not adept at using the mouse in general, so I want to make it as easy on them as possible.
