What is the traditional keyboard for Thinkpad laptops? What is the technical term for it? (It is better to have a relevant introduction) Thank you.

Full name: seven-row floating keyboard.

History: 20 years, since the first ThinkPad in 1992.

Features: 1, X drum-shaped architecture, this keycap under the architecture of the complexity of the general keyboard, so that the key range, the feedback force is balanced and stable, is the fundamental reason for its feel good.2, small red dot, pointing stick, is a set of mouse.3, blue enter key, with different colors to mark the high-frequency keys.4, Function key is located in the lower left end of the keypad, it is convenient to locate the function of the Function directly.5, anti-splash Spill-resistant, liquid will flow out from underneath the laptop when it enters.6. Quick release, usually only need to remove 2~3 screws from D side to take the keyboard down directly from C side without dismantling the laptop.

Update: The new generation of keyboards is called the six rows of isolated keyboards, T, X, W series retained 1, 2, 4, 5, 6 three features, the essence is still there, personal experience confirmed. Edge and X1 Carbon have 1, 2, 4, 5, but Carbon's keyboard feels good, Edge can not, especially the last row (that is, the row of keys containing spaces) oversized, and the above rows are not coordinated, the reason for this is the integration of the size of the arrow keys, just like the Macbook's keyboard.
