What are the functions of f2 keyboard?
Function key F2 is a function key of the system, generally used to rename files.
The function of the F2 key is: renaming. When a folder is selected in the resource manager, pressing F2 will rename the current folder.
The FN key is mostly a key on laptops. Use it with the F1~12 keys to form a key combination. To make up for the lack of keyboard keys on the laptop.
It is primarily a key found in the lower left corner of laptop and netbook keyboards. Some laptops place the control keys in the lower left corner, with Fn in the bottom row of the keyboard and the second row from the left. The "Fn" multi-purpose imprint also has keys in green, purple and phase combinations to perform functions of the same color as another key.
These key combinations can be used to adjust hardware (hibernate, switch displays), or supplement the omitted desktop buttons on laptops.
Related introduction:
Conventional keyboards include mechanical keys and capacitive keys. Among industrial computer keyboards, there is also a keyboard with light touch membrane keys. Mechanical keyboard is the earliest structure adopted. It is generally similar to the principle of contact switch to make the contacts conduct or disconnect. It has the characteristics of simple process, convenient maintenance, average feel, loud noise and easy wear and tear.
Most cheap mechanical keyboards use copper springs as elastic materials. The copper plate loses elasticity easily, and the use time is long, which increases the failure rate of capacitive keyboards. It is based on a capacitive switch keyboard. Its principle is to change the distance between electrodes by pressing a button to produce a change in capacitance, temporarily forming conditions that allow the oscillation pulse to pass.
Theoretically, this switch is non-contact, has little or negligible wear rate, no danger of bad contact, low noise, easy to control by hand, can produce a high-quality keyboard, But the process is more complex than mechanical construction. There is also an IPC keyboard that uses light touch membrane keys for complete sealing and is only suitable for special occasions.
