Reaching over the number pad, that is located on the right side of a traditional keyboard, to mouse can lead to shoulder discomfort for some users.
We recently had the opportunity to trial the Number Slide Mini Keyboard with Retractable Number Pad by Posturite. This product provides the advantages of a compact keyboard, namely a decreased lateral reach to the mouse, without sacrificing the number pad.
For those of us that use the number pad intermittently, it slides easily under the keyboard when not in use and allows for typing in a more neutral posture.
The feel of this keyboard is similar to the low tactile feedback provided by a laptop keyboard and may not be well suited to those who prefer more vertical key travel and those who have bigger hands or are broader through the shoulders.
For petite workers who only use the number pad intermittently, this keyboard provides a good option.
