    If you want the detector to behave almost like pedestals/buttons,
    set speed rather high, like &lt;detection speed&gt; 1.0.</td>

    "move", thus how fast the symptoms strike the host.</td>

		<td>
@ref page_type_62
		</td><td>    The &lt;casting speed&gt; defines the spellcasting speed of the wall.
    You can fine-tune how long the duration between two casts shall
    be. If you want to create a wall that can be activated (cast per
    trigger) via connected lever/button/etc, you must set "speed 0".</td>
	</tr>
	<tr>
		<td>
@ref page_type_55
		</td><td>    The &lt;marking speed&gt; defines how quickly it will mark something
    standing on the marker. Set this value rather high to make
    sure the player really gets his mark. I think &lt;marking speed&gt; 1.0
    should do fine.</td>

		<td>
@ref page_type_212, @ref page_type_28
		</td><td>    The &lt;speed&gt; determines how fast a monster will both move
    and fight. High &lt;speed&gt; makes a monster considerably stronger.</td>

	<tr>
		<td>
@ref page_type_40
		</td><td>    The movement speed value determines how fast a chain of
    these movers will push a player along (default is -0.2).</td>
	</tr>
	<tr>
		<td>
@ref page_type_138
		</td><td>    The higher the &lt;drowning speed&gt;, the faster will players and items
    sink into the swamp. Swamp with very high &lt;drowning speed&gt; can be a nasty
    and unexpected death-trap. Players should get a warning before such areas.</td>
	</tr>
	<tr>
		<td>
@ref page_type_41
		</td><td>    If the &lt;activation speed&gt; is nonzero, the teleporter will
    automatically be activated in regular time-intervals. Hence, the
    player can just step on it and gets teleported sooner or later.
    The duration between two activates depends on the given value.
    Default in the teleporter arch is &lt;activation speed&gt; 0.1.

    VERY IMPORTANT: If you want to have your teleporter activated via
    button/handle/magic_ear/etc, you must set &lt;activation speed&gt; to zero!</td>
