Kinesis KB210USB Adjustable Ergonomic USB/PS2 Keyboard - Manual (Page 10)

Layout of keyboard
The Maxim adjustable ergonomic keyboard has a layout very similar to that of a
traditional keyboard or a full size laptop computer. This provides virtually instant
adaptation for new or occasional users. The few differences in navigation and
editing key arrangement reduce the width of the keyboard. This improves the
positioning of the mouse for right-handed users of the Maxim keyboard,
compared to a traditional keyboard.
For intensive numeric data entry, most users will want a separate numeric keypad
which can be moved out of the way when using the mouse. Consider the Kinesis
AC210USB, which also serves as a USB hub and provides extra productivity
keys.
