Bill Gross used this Bloomberg keyboard in his work at Pacific Investment Management during the 1990s and 2000s. The Bloomberg keyboard is similar to other QWERTY keyboards in its layout, but it replaces many of the generic function keys with finance specific hotkeys that can access real time security options for a variety of sectors. There are also specific keys for calling up quotes, and selling or buying stocks and bonds. The keyboard is color coded in red, green, and yellow to help traders quickly identify the keys they need. The Bloomberg keyboard originally came with Bloomberg hardware and needed an annual subscription to Bloomberg’s data to work. The subscription remains necessary, but there are now Windows clients to use in conjunction with the keyboard, removing the need for the “Bloomberg boxes.”
