Located at the top of the keyboard, these keys perform special tasks like help (F1), refresh (F5), or system functions depending on the software.
- Control keys:
Keys such as Ctrl, Alt, Shift, Esc, and Windows key are used in combination with other keys to perform commands.

Keys like Enter, Spacebar, Backspace, Delete, and Tab are used for specific actions like spacing, deleting, or moving to the next field.
