Tooltip

Contextual hint. It opens on hover and also on focus, closes with Escape, and exposes its text through aria-describedby; a hint that exists only visually never reaches screen reader users.

Placements

Shows above Shows below Shows on the right
@components.Tooltip(components.TooltipProps{ID: "tip", Text: "Shows above"}) { ...trigger... }

From the keyboard

Tab to the button: the hint opens on focus, no mouse needed. Escape closes it.

Saves without closing the form
Tabbing to the trigger opens the hint; Escape closes it.
