The 75 Keyboard: A Unique and Fascinating Typing Experience
The 75 keyboard, also known as the 75% keyboard or 75% layout, is a typing layout that originated in the 1970s. It is characterized by a unique arrangement of keys that allows users to type with a 75% efficiency rate, meaning that they can type at a rate of 75 words per minute compared to the standard 60 words per minute.
How Many Keys Does a 75 Keyboard Have?
A standard QWERTY keyboard has 104 keys, including the space bar, shift keys, and navigation keys. However, the 75 keyboard has a significantly reduced number of keys, with a total of 61 keys. This reduction in key count is due to the unique layout of the keyboard, which was designed to reduce finger movement and alternating hand use.
The 75 Keyboard Layout
The 75 keyboard layout is a modified version of the QWERTY layout, with the following key differences:
- Numpad: The 75 keyboard has a separate numpad located on the right-hand side of the keyboard, which contains the numbers 0-9.
- Navigation keys: The navigation keys (up, down, left, and right arrow keys) are located on the top row of the keyboard, with the left arrow key being the most frequently used.
- Function keys: The function keys (F1-F12) are located on the top row of the keyboard, with the F1 key being the most frequently used.
- Special keys: The 75 keyboard has a separate set of special keys, including the "Shift" key, which is used to switch between the QWERTY layout and the 75 layout.

The 75 keyboard layout has several benefits, including:
- Improved typing efficiency: The reduced number of keys on the 75 keyboard allows users to type at a faster rate, with a 75% efficiency rate compared to the standard 60 words per minute.
