Technical symbols are essential for programmers, engineers, mathematicians, and anyone working with specialized notation. This collection includes APL operators, keyboard control characters, electrical symbols, and computing notation marks that you will not find easily on standard keyboards.
From the command key and option symbol used in Mac documentation to the null symbol and logical operators used in formal logic, these characters serve critical roles in technical writing. Developers need them for documentation, scientists use them in papers, and system administrators reference them in guides.
Our technical symbol collection covers keyboard symbols, logical operators, set theory notation, electrical notation, and computing characters. Each symbol copies with one click and works in code editors, documentation, presentations, and any text field across all platforms.
Pro tip: bookmark this page if you write technical documentation. Having quick access to keyboard symbols, logical operators, and computing characters saves significant time compared to hunting through character maps or memorizing alt codes.
How this Technical Symbols collection is organised
This Technical Symbols collection gathers every Unicode character that belongs in the category plus the close relatives people tend to search for in the same sitting. The grid above is grouped so the most-copied items sit at the top — for Technical Symbols that means the canonical Unicode characters first, close stylistic relatives second, and the longer tail of rarer variants at the bottom. Click any tile and the character goes straight to your clipboard; a small toast at the bottom-right confirms the copy so you can keep browsing.
What makes this collection different from a generic "copy-paste site" is that every character here is real Unicode text, not an image. That means the character survives every redraw: if you paste it into Instagram, Discord, TikTok, a Word document, a Google Doc, a Figma file or a Markdown README, the recipient's device renders it with its own font, at the size of the surrounding text, with correct accessibility semantics for screen readers. No installation, no app permission, and nothing leaves your browser.

Absolutely! Symbols like ⌘ (Command), ⌥ (Option), ⇧ (Shift), ⌃ (Control) are perfect for keyboard shortcut documentation and Mac user guides.
Text symbols like ⚙ ⚠ ☢ display consistently across all devices and in all fonts. Emojis may look different on iOS vs Android vs Windows. For documentation, text symbols are more professional.
