Disable Touchpad on Dell Laptop

Problem
Ever frustrated with Touchpad being overly sensitive?

I frequently got random mouse movements and clicks while using Laptop's keyboard. They are caused by the Touchpad being overly sensitive. It is especially a problem when I am using remote desktop working on another computer. I guess the Touchpad sensitivity settings does not work on remote desktop client?

And this is a major frustration, because when I finish typing a line of code, they frequently show up on the wrong line, and did not show up anywhere at all, because the random mouse clicks has took their focus away.

Research
Today, finally it struck me that I should disable this thing. And turns out the latest DELL tool has some nice options available. For one thing, I can permanently enable/disable "Pointing Stick", "Pointing Stick Buttons", "Touchpad", and "Touchpad Buttons". But, there is also a very nice feature called: "Disable Touchpad/Point Stick when external USB mouse is present". This is really a very user friendly feature that I never thought of searching for before.

Conclusion
I put a check next to the option:  "Disable Touchpad/Point Stick when external USB mouse is present", and got a wireless mouse. Problem solved. Happily typing code again.

It was a very useful tool for me.

Portable Mouse with a Hook or Loop

Goal: to allow portable mouse to be even more portable

Going to meeting with a laptop, a pen and notebook (made with paper) and a mouse can be a handful (not to mention when you have a cup of coffee). What if we have a hook or ring on the mouse so that it can dangle on a finger (or belt?).
 
Potential Solutions
- retractable ring
- foldable ring
- hook

Need to pay attention of location of ring or hook so that they don't interfere with normal mouse use.
