        <para>To perform a simulated secondary click, the user has to keep the

        the pointer for the time determined by the delay slider of the
        Simulated Secondary Click feature. While the <mousebutton>primary

        <para>If the user releases the <mousebutton>primary mouse

        <mousebutton>secondary mouse button</mousebutton> click. In fact,
        mousetweaks creates this simulated <mousebutton>scondary mouse
        button</mousebutton> click as soon as the user releases the the
        <mousebutton>primary mouse button</mousebutton>.</para>

        <note>
          <para>On browser links, the simulated secondary click behaves
          differently: it does not wait for the user to release the
          <mousebutton>primary mouse button</mousebutton> before creating the
          simulated secondary click; the secondary click is created as soon as
          the time delay has elapsed. Previous versions of mousetweaks always
          behaved like this; but this behaviour had to be modified because of
          changes to the X server.</para>
        </note>

        <para>The explanations above assumed that the pointer did not move
        between the <mousebutton>primary mouse button</mousebutton> press and
        release. If the pointer gets moved before the <mousebutton>primary
        mouse button</mousebutton> is released, no simulated secondary click
        will be created. Consequently, to cancel an initiated secondary click,
        the user only has to move the pointer before releasing the
        <mousebutton>primary mouse button</mousebutton>.</para>

        <para>As the Simulated Secondary Click does not discard
        the<mousebutton> primary mouse button</mousebutton> press and release,
        the resulting primary click occurs just before the secondary click
        created by mousetweaks. Consequently, the simulated secondary click
        behaves a bit differently than the normal secondary click, because the
        latter is usually not preceeded immediately by a <mousebutton>primary
        mouse button</mousebutton> click. For example:</para>

        <itemizedlist>
          <listitem>
            <para>选中多个项时不能执行次要按钮点击动作，因为次要按钮点击前的那次主要按钮点击将会取消选择。</para>

            secondary click, the latter by the primary click preceding the

        <para>Looking at it the other way, it is no possible to perform a long
        motionless <mousebutton>primary mouse button</mousebutton> press,
        without also triggering the secondary click. This may also have
        unexpected consequences for some users. For example:</para>

          <listitem>
            <para>When releasing the primary button after keeping it pressed
            on the arrow of a scrollbar for more than the delay time, the

            behaviour of a secondary click on an arrow of a scrollbar.</para>

            <tip>
              <para>To avoid that the scrollbar jumps to the bottom, simply
              move the pointer away from the arrow of the scrollbar before
              releasing the primary button; this way, the initiated simulated
