They are used extensively in word processing, email composition, coding, and various other applications where written language is employed.

2. Punctuation Marks: Punctuation marks serve to clarify the structure and meaning of written language by indicating pauses, endings, quotations, and separations within sentences. Beyond the commonly known marks such as periods, commas, question marks, and exclamation marks, there are also lesser-known symbols like en dashes (–), em dashes (—), ellipses (…), and interrobangs (‽). These symbols contribute to nuanced expression and effective communication in written text.

3. Special Characters: Special characters encompass a broad range of symbols that serve specific functions in different contexts. They include currency symbols (e.g., $, €, £, ¥), mathematical symbols (e.g., +, -, ×, ÷, =), logical operators (e.g., ∧, ∨, ¬, →, ↔), arrows (e.g., ←, ↑, →, ↓), and various other symbols used in technical writing, scientific notation, and graphical user interfaces. Special characters are indispensable for expressing mathematical equations, representing data, and conveying complex concepts.

4. Function Keys: Function keys (F1-F12) are keys designated to trigger predefined functions in software applications and operating systems. While F1 commonly invokes a help menu, other function keys may perform tasks such as opening specific features or executing macros. Function keys are programmable in some contexts, allowing users to customize their functionality according to their preferences and workflow.

5. Modifier Keys: Modifier keys alter the behavior of other keys when pressed simultaneously. The Shift key modifies the output of alphanumeric characters, enabling the input of uppercase letters and symbols located above numerals. The Ctrl (Control) key is used in combination with other keys to execute commands, such as Ctrl+C for copying and Ctrl+V for pasting. Similarly, the Alt (Alternate) key, also known as the Option key on Mac keyboards, provides alternate functions for certain commands.

6. Navigation Keys: Navigation keys facilitate movement within documents, web pages, and user interfaces. In addition to the arrow keys for directional movement, there are dedicated keys for moving the cursor to the beginning or end of a line (Home and End keys), scrolling through content (Page Up and Page Down keys), and jumping between words or paragraphs (Ctrl+Arrow keys). These keys enhance navigation efficiency during text editing and browsing activities.
