What it is
A question-mark or labeled help control provides an explicit way to request an explanation. The resulting information should be relevant to the immediate context.
When to use it
Name the help topic and let people dismiss the explanation without losing their work.
Know the difference
A tooltip appears on hover or focus; a help button is an explicit action to request assistance.
Across platforms
Web
Use a native button for an action and an anchor for navigation. Preserve keyboard activation and a visible focus indicator.
iOS · iPadOS · Android
Provide a comfortable touch target, use familiar system symbols when appropriate, and show a clear pressed or selected state.
macOS · Windows · Linux
Keep pointer, keyboard, and focus behavior consistent. Common commands can additionally expose a menu item or keyboard shortcut.
