More on this type of keyboard...
The AccuType ThinkPad Keyboard was Lenovo's replacement to the long line of classic Model M6/M6-1 derived keyboard designs introduced in 2011 with Lenovo ThinkPad X1 and deployed as the sole ThinkPads keyboard design the following year. The AccuType's keytops are wider than before and the switches have reduced key travel, but they still largely resemble the feel of previous classic ThinkPad keyboards. All standard versions feature a TrackPoint IV pointing stick.
