Matias today announced the OS X Keyboard, which features an extra Control key (where Caps Lock normally is) along with features inherited from its popular Tactile Pro keyboard. Like the Tactile Pro, the OS X Keyboard has all of the Option and Shift-Option symbols printed on the keys, making it easier to type characters such as ™ € £ © and others. Unlike the Tactile Pro, the OS X Keyboard uses rubber dome keyswitches, for quieter operation and tactile response. The US$39.95 keyboard will make its debut next week at Macworld Expo in San Francisco.
