Prior to choosing this configuration I didn’t see any video so I thought it might be of interest if you look for an alternative to the traditional mouse pointing device.
No commentary, so it is rather dull otherwise than showing the movement involved in this configuration.
90% of the time I use the keyboard to click, and seldom use the Kensington buttons.
The only very minor inconvencience I that the keyboard slips a little sometimes, but too lazy to fix this so far.
Apart from that, i really love this !
