Labcenter maintains official forums where users share library components. Search for "4x4 keypad" or "matrix keypad." You will often find links to .ZIP files containing KEYPAD4X4.LIB and KEYPAD4X4.IDX.
A 4x4 keypad is an input device arranged in a matrix of four rows and four columns. Unlike connecting 16 individual buttons (which would consume 16 GPIO pins), the matrix configuration requires only 8 pins (4 for rows and 4 for columns).
The microcontroller scans the matrix by sending signals through the rows and reading the columns to detect which key has been pressed. This method saves precious I/O pins on microcontrollers like the Arduino, PIC, or 8051.
Congratulations! You have completed the Proteus 4x4 Keypad Library Download and installation.
In Miscellaneous library, there is a calculator-style keypad. It is 4x4 but may not be labeled as rows/columns intuitively. You can remap its connections.
