Logitech TrackMan Marble

Logitech TrackMan Marble It enjoys concerning the size of a pea, which was very easy to roll with your thumb. There are 3 buttons, two are the normal mouse left as well as ideal buttons and also the 3rd is a drag-lock button, with a little LED next to it which lights up when drag-lock is involved. That 3rd switch made all the difference in the world to the use of the Thumbelina, because attempting to click-and-drag indifferently, with just the two fundamental buttons, was almost impossible.

The Thumbelina has a PS/2 port as well as featured a PS/2-Serial adapter. It worked when I linked it to the T400, as well as was identified by Linux as a “Common PS/2 computer mouse”. As quickly as I started using it I bore in mind among the much more annoying aspects of it – when it is properly oriented in your hand (to ensure that rolling the ball up moves the cursor up), the cable comes out of the bottom. It would have been a lot more convenient if the cable had actually gotten on the top.

The arrow movement was jumpy as well as imprecise, as well as arrow speed was much as well reduced. The button instantly to the right of the ball is the “left” switch, as well as the one above that in the top-right edge, is the “appropriate” button. The switch to the left of the ball is drag-lock, and also it is fairly brilliant. A regular mouse button click in fact generates 2 occasions, a button press complied with by a button release. The drag-lock button on the Thumbelina just produces one event each time you click it, alternating in between button 1 press as well as button 1 release.
