Search Field
The search box at the head of a list, with its keyboard shortcut.
Default
Press / anywhere on the page to focus it. The hint gives way to a clear button once there is a query; Escape clears, then leaves the field.
Sizes
Match the controls beside it: 32, 36, or 40px, like Input. Bind a shortcut on one field per page; pass shortcut={null} on the rest.
