What Are Computer Symbols?

Computer symbols are characters or visual marks used to represent information, actions, commands, values, relationships, or concepts in digital environments.

Some are typed directly from a keyboard, such as @, #, $, %, and &. Others may need a symbol picker, character viewer, character map, special keyboard shortcut, or copy-and-paste method.

It is useful to understand that symbols, characters, and icons are related but not identical terms.

Symbols vs Characters

A character is a basic unit of text. It can be a letter, number, punctuation mark, or special character.

For example:

• A is a letter character.
• 7 is a number character.
• @ is a symbol character.
• © is a special symbol character.

A symbol generally communicates a particular meaning or function.

Symbols vs Icons

An icon is usually a graphical representation of an object, action, feature, or status.

For example:

• @ is a text symbol.
• © is a special character.
• A Wi-Fi graphic is an interface icon.
• A trash-can graphic commonly represents deletion or the Recycle Bin.

Windows includes desktop icons such as This PC, Recycle Bin, Network, and User’s Files.

Why Are Computer Symbols Important?

Symbols make digital communication shorter and easier to understand. Instead of writing an entire instruction, an interface can use a familiar icon or symbol.

They are used in:

• Emails
• Websites
• Documents
• Computer programs
• File names
• Mathematics
• Social media
• Search
• Software interfaces
• Keyboard shortcuts
• Computer commands

Its precise meaning depends on the application.

Computer Symbols on Windows

Windows provides several ways to enter symbols and special characters.

Windows Symbol Panel

On Windows, pressing Windows key + period (.) opens the emoji panel during text entry. From there, users can select the Symbols section to browse available characters.

This is useful when the desired symbol is not printed on the physical keyboard.

Alt Codes on Windows

Some Windows symbols can be entered using Alt codes.

For example, Microsoft documents:

• Alt + 0169 — ©
• Alt + 0174 — ®
• Alt + 0153 — ™
• Alt + 0149 — •
• Alt + 0167 — §
• Alt + 0150 — –
• Alt + 0151 — —

These Alt-code methods require the numeric keypad; the number row across the top of a keyboard does not work for these traditional Alt-code entries.

Character Map

Windows also includes Character Map, which lets users view, select, copy, and paste special characters that may not be available directly from a standard keyboard.

A simple method is to search for Character Map from Windows Search, select a character, copy it, and paste it into the desired application.

Computer Symbols on Mac

Mac computers provide built-in tools for finding symbols and special characters.

Character Viewer

Mac’s Character Viewer lets users browse and insert symbols, emoji, accented letters, and characters from other writing systems. Apple documents opening it with Fn/Globe-E or through Edit > Emoji & Symbols.

In supported apps such as Pages, Control-Command-Space can also open the Character Viewer.

Keyboard Viewer

Mac’s Keyboard Viewer displays an onscreen version of the current keyboard layout.

It can help users discover where symbols are located and see additional characters available with modifier keys such as Option and Shift.

Mac Modifier Symbols

Mac menus often display special symbols for keyboard shortcuts.

Common examples include:

Key	Common Symbol
Command	⌘
Shift	⇧
Option	⌥
Control	⌃
Escape	⎋
Return	↩
Delete	⌫
Up Arrow	↑
Down Arrow	↓
Left Arrow	←
Right Arrow	→

Apple identifies these symbols as representations of modifier and special keys used in Mac menu shortcuts.

How to Type Computer Symbols

There are several ways to type a computer symbol, depending on your device and the symbol you need.

Using the Shift Key

For symbols printed above numbers or other keys, hold Shift while pressing the appropriate key.

On a standard US keyboard, this produces symbols such as:

! @ # $ % ^ & * ( )

Keyboard layouts vary, so the same symbol may appear in a different location on another layout.

Using Windows Symbol Tools

On Windows, press:

Windows + .

Then choose the Symbols section and select the character you need.

Using Alt Codes

If you have a numeric keypad, some special characters can be entered with Alt codes.

For example:

Alt + 0169 → ©

Alt + 0174 → ®

Alt + 0153 → ™

The availability of a particular code and the exact insertion behavior can depend on the application and character system being used.

Using Character Map

Windows Character Map is useful when you want to browse characters visually, select one, copy it, and paste it into another application.

Using Character Viewer on Mac

On Mac, open Character Viewer and search or browse for the required symbol. Apple says the viewer can be used for emoji, symbols, accented characters, and characters from other languages.

Copy and Paste

Copy and paste is often the easiest method when you only need a symbol once.

For example:

© ® ™ ✓ → ← ↑ ↓ ∞ √

You can copy a symbol from a trusted source and paste it into a compatible document, message, webpage, or application.
