Bug 133620 [FieldAssist] auto activation of proposal popup should be canceled on keystroke
I20060328-0010 Auto activation of the proposal popup should be canceled on keystroke. Steps: - open Find/Replace dialog, activate regex - type "\rrrrrrr" as fast as possible => after a few "r"s, the proposal popup appears at the last "r" inserted This is not the intent of the "auto activation with delay" feature. Auto activation is intended to help the user if he stops typing and starts to think about possible completions. It should be triggered when the user types "\" and then waits a while, but the popup should not appear when the user continues typing after the trigger character.

*            no content proposal is available.
	 * @param keyStroke
	 *            the keystroke that will invoke the content proposal popup. If
	 *            this value is <code>null</code>, then proposals will be
	 *            activated automatically when any of the auto activation
	 *            characters are typed.
	 * @param autoActivationCharacters
	 *            An array of characters that trigger auto-activation of content
	 *            proposal. If specified, these characters will trigger
	 *            auto-activation of the proposal popup, regardless of whether
	 *            an explicit invocation keyStroke was specified. If this
	 *            parameter is <code>null</code>, then only a specified
	 *            keyStroke will invoke content proposal. If this parameter is
	 *            <code>null</code> and the keyStroke parameter is
	 *            <code>null</code>, then all alphanumeric characters will
	 *            auto-activate content proposal.
