Subject: [PATCH] Use input event not keyup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The `oninput` event is a more performant way to detect changes to a
textbox’s contents (compared to `onkeydown`, `onpaste`, etc).

It’s not supported in older browsers, but since this is a likely to be
used by platform admin users only that’s OK.
