Draw and labelled computer keyboard

A standard computer keyboard is typically divided into several functional sections. Here's a description of these sections and their common labels:

1. Function Keys (F1-F12): Located at the very top row of the keyboard. These keys perform specific functions depending on the program being used (e.g., F1 for help, F5 for refresh).
2. Alphanumeric Section (Main Typing Area): This is the largest section, located in the center-left. It contains:
   • Letter Keys (A-Z): Arranged in a QWERTY layout (or other regional layouts like AZERTY, QWERTZ).
   • Number Keys (0-9): Located above the letter keys.
   • Symbol Keys: Such as !, @, #, $, %, ^, &, *, (, ), -, =, +, [, ], {, }, , |, ;, :, ', ", ,, <, ., >, /, ?, ~.
   • Modifier Keys:
     • Shift: Used to type uppercase letters and the upper symbols on number/symbol keys.
     • Caps Lock: Toggles uppercase typing on/off.
     • Tab: Moves the cursor to the next tab stop or indents text.
     • Ctrl (Control): Used in combination with other keys for shortcuts (e.g., Ctrl+C for copy).
     • Alt (Alternate): Also used in combination with other keys for shortcuts.
     • Windows Key / Command Key (Mac): Opens the Start menu or performs system-level shortcuts.
     • Spacebar: Inserts a space.
     • Enter / Return: Confirms input or moves to the next line.
     • Backspace: Deletes characters to the left of the cursor.
3. Navigation and Editing Keys: Located to the right of the alphanumeric section. These include:
   • Insert: Toggles between insert and overwrite modes.
   • Home: Moves the cursor to the beginning of a line or document.
   • Page Up (PgUp): Scrolls up one page.
   • Delete (Del): Deletes characters to the right of the cursor.
   • End: Moves the cursor to the end of a line or document.
   • Page Down (PgDn): Scrolls down one page.
4. Arrow Keys: A set of four keys (Up, Down, Left, Right) arranged in an inverted T-shape, typically located below the navigation keys. Used for moving the cursor or navigating through menus.
5. Numeric Keypad: Located on the far right side of full-size keyboards. It resembles a calculator keypad and includes:
   • Number Keys (0-9): For quick numerical input.
   • Arithmetic Operators: +, -, *, /.
   • Decimal Point (./,).
   • Enter Key.
   • Num Lock: Toggles the numeric keypad between number input and navigation functions (e.g., 7 can be Home, 1 can be End).
6. Special Keys:
   • Esc (Escape): Typically in the top-left corner, used to cancel operations or close menus.
   • Print Screen (PrtSc): Captures a screenshot.
   • Scroll Lock: An older key, sometimes used to lock scrolling.
