A keyset or chorded keyboard is a computer input device that allows the user to enter characters or commands formed by pressing several keys together, like playing a "chord" on a piano. The large number of combinations available from a small number of keys allows text or commands to be entered with one hand, leaving the other hand free. A secondary advantage is that it can be built into a device that is too small to contain a normal-sized keyboard.

Touch typing is a style of typing.

Both two-handed touch typing and one-handed touch typing are possible.
Caps Lock⇪ Caps Lock is a button on a computer keyboard that causes all letters of bicameral scripts to be generated in capital letters. It is a toggle key: each press reverses the previous action. Some keyboards also implement a light to give visual feedback about whether it is on or off. Exactly what Caps Lock does depends on the keyboard hardware, the operating system, the device driver, and the keyboard layout. Usually, the effect is limited to letter keys. Letters of non-bicameral scripts and non-letter characters are generated normally.

The Blickensderfer typewriter was invented by George Canfield Blickensderfer (1850–1917) and patented on April 12, 1892. Blickensderfer was a nephew of John Celivergos Zachos, the inventor of the stenotype. Two models, Model 1 and Model 5, were unveiled to the public at the 1893 World's Columbian Exposition in Chicago. The Model 5 was a stripped-down version of the bigger, more complex Model 1. These machines were intended to compete with larger Remington, Hammond and Yost typewriters, and were the first truly portable, full-keyboard typewriters. The design also enabled the typist to see the typed work, at a time when most typewriters were understrike machines that concealed the writing. When Blickensderfer unveiled his small Model 5, its compactness and novel features attracted huge crowds and many orders.
