I have noticed that I often brush the touchpad of my agora whilst typing, and this often moves the cursor to another line in the text I am typing, or changes focus to a different window. It can be very frustrating!
Neerav Bhatt also mentioned that he was having this problem, and I flashed back to all my google searching when I was trying to enable the touchpad in Ubuntu Netbook Remix. I came across some information on how to disable the touchpad, which was completely the opposite to what I was trying to achieve. Flash forward to today, and it now seems pretty useful!
I have dug up that information, and now I have my touchpad disabled whilst I type. When I stop typing, 1 second after the last key press, the touchpad is re-enabled.
