- Don’t use a tooltip to restate a button name that’s already shown in the UI.
- When a control or UI element is unlabeled, use a simple, descriptive noun phrase. For example: “Highlighting pen”. Only capitalize the first word (unless a subsequent word is a proper noun), and don’t use a period.
- For a disabled control that could use an explanation, provide a brief description of the state in which the control will be enabled. For example: “This feature is available for line charts.”
- Only use periods for complete sentences.

For a UI label that needs some explanation:

- Briefly describe what you can do with the UI element.
- Use the imperative verb form. For example, "Find text in this file" (not "Finds text in this file").
- Don't include end punctuation unless there is at least one complete sentence.

For a truncated label or a label that’s likely to truncate in some languages:

- Provide the untruncated label in the tooltip.
- Don't provide a tooltip if the untruncated info is provided elsewhere on the page or flow.
- Optional: On another line, provide a clarifying description, but only if needed.
