12 UI Icons Everyone Uses but Nobody Can Name

Three stacked horizontal lines: two buns, one patty. Designed by Norm Cox in 1981 for the Xerox Star — the first commercial GUI workstation — as a compact way to say "a list of things lives here." It hibernated for 30 years, then mobile screens made it the default pattern for hidden navigation drawers.

Three dots stacked vertically, like meat on a skewer. Popularized by Google's Material Design, where it's formally the "overflow menu" — the place actions go when a toolbar runs out of room. The food name stuck because design teams needed to distinguish it from its horizontal sibling in conversation.

Three dots in a row — meatballs on a plate. Functionally identical to the kebab, but it reads as punctuation ("…more") rather than a skewer, which is why iOS and most web apps prefer it inline with horizontal content: table rows, toolbars, tweet footers.

A 3×3 grid of squares or dots, named after the compartments of a Japanese bento box. Microsoft's design teams call the same pattern the waffle. You know it as the app-switcher in Google Workspace and Microsoft 365 — the icon that says "all our other products live here."

Stacked horizontal lines of decreasing width — shaved meat on a döner kebab spit. It completes the food-menu family, and unlike its cousins it carries meaning in its shape: the taper implies narrowing a set down, which is why it conventionally means filtering (or sorting) rather than navigation.

Two columns of dots (or two short lines) marking where you can grab an element to reorder it. Designers call it the grabber or drag handle; the six-dot variant gets nicknamed "braille" because it resembles a braille cell. It's one of the few icons whose entire job is to communicate a physical affordance.

Sharing never got one icon — it got two. Apple's is a box with an arrow escaping upward (officially the "action" or Share button, introduced with iOS 7). Android's is three nodes joined by two lines — a graph of content traveling from one point to others. Same verb, two dialects; users of each platform barely recognize the other's icon.

The 3.5-inch diskette held about 1.44 MB and died commercially two decades ago — yet it remains the universal symbol for "save," because when GUIs standardized in the late '80s and '90s, saving literally meant writing to this object. The medium vanished; the icon detached from its referent and survived as pure symbol. Most users under 25 have never touched one and understand it perfectly.

Every database icon is a stack of short cylinders — because early computer storage physically was a cylinder: magnetic drum memory in the 1950s–60s, then platter stacks inside hard drives. Engineers drew storage in system diagrams as the shape of the hardware, and the convention outlived three generations of storage technology. Your data now lives in flash cells and distributed object stores; the icon still remembers the drum.

The ⌘ on every Mac keyboard is the Saint John's Arms, a knot-shaped heraldic symbol centuries old, still used on Nordic road signs to mark places of interest. In 1983, Steve Jobs vetoed putting the Apple logo on menu shortcuts ("we're taking the Apple logo in vain!"), and designer Susan Kare found this glyph while paging through a symbol dictionary. It has meant "command" ever since.

The line-and-circle on every power button is literally binary: a 1 (on) breaking into a 0 (off). It descends from IEC standards where "|" meant power on and "○" meant power off; the merged glyph — the line piercing the broken circle — officially means standby. One of the only icons in daily use that encodes its meaning in a number system.

Designers use these interchangeably; they aren't. A chevron is the wide V-shape (❯) meaning "navigate or expand in this direction." A caret is the small typographic wedge (ˆ) that flips to toggle dropdowns. A disclosure triangle is the small filled triangle (▸) from classic Mac OS that rotates to expand tree views. Three glyphs, three interaction promises — mixing them muddies what a click will do.
