What the row of buttons is, and why it changes with what you copied.
Hover a row for a moment, or press ⇧, and a panel opens beside the popup: the item in full, the counters, and a row of one-tap buttons called chips.
The chips are built from what you copied. A colour offers HEX, RGB, HSL, SwiftUI, a CSS variable and a Tailwind class. JSON offers pretty-print, minify and keys. Plain text offers eleven case styles, the cleaners and the encoders. Klipto detects twenty-two content types, so the row is never a wall of buttons that do not apply.
The chevron at the end of the row opens the full list for that type, including the chips you switched off.
Tab walks the controls and Space presses the focused one, so the panel works without the mouse.
