Editing IBM Space Saving Keyboard (section)

==Features and design==

The number pad was integrated with the keyboard. Shift-NumLk would switch normal alphabet keys to keypad function. The top row 7, 8, 9 keys stayed the same, the U, I, O keys became 4, 5, 6, respectively, and J, K, L became 1, 2, 3, respectively. Lastly, M became 0. If Shift was pressed while in NumLk mode, those keys became navigation keys, with the same functions as the dedicated keys down the right side of the keyboard (Insert, Home, PgUp, Del, End, PgDn and the 4 arrow keys).

Unfortunately, the keyboard has no lights to indicate the mode of the keys.
