Fader

A continuous value along a line: a native range whose cap rides in a slot cut into the plate, with a printed scale.

Drag a cap, or focus it and use the arrow keys, Page Up/Down, Home and End.

• Name it with a label or aria-label; show the value beside or under it in tabular figures.
• For values with units, set aria-valuetext (“−6 dB”) as it moves; the native range only announces the number.
• The focus ring draws on the cap.
