Search shortcut triggers for keys that aren’t `k`

[flying-sheep]

This code triggers for all events where event.key contains “k” or “K”, e.g. event.key === "Backspace".

This means that pressing ⌘⌫ toggles the search popup instead of deleting a word as it should.

	/k/i.test(event.key)
	) {
	event.preventDefault();

The regex should be /^k$/i instead, as done in #1646
