title: xmodmap KeyPress Event to ButtonPress event
body: <p>I asked this already on unix.stackexchange but no luck so far, so I'm posting it here. Hopefully someone knows the answer.</p>
  
  <p>I just got a logitech t400 mouse and everything is working well, except I want to remap the "top" part of the middle mouse to actual middle mouse function.</p>
  
  <p>When I run xev, and capture the clicks, all the mouse buttons return a ButtonPress/ButtonRelease event but the top part of the middle button returns a KeyPress/KeyRelease event as :</p>
  
  <pre><code>KeyPress event, serial 35, synthetic NO, window 0x5200001,
  root 0x31d, subw 0x0, time 630089839, (80,128), root:(2871,588),
  state 0x10, keycode 133 (keysym 0x31d, (no name)), same_screen YES,
  XLookupString gives 0 bytes: 
  XmbLookupString gives 0 bytes: 
  XFilterEvent returns: False
  
  KeyRelease event, serial 36, synthetic NO, window 0x5200001,
  root 0x31d, subw 0x0, time 630089983, (80,128), root:(2871,588),
  state 0x50, keycode 133 (keysym 0x31d, (no name)), same_screen YES,
  XLookupString gives 0 bytes: 
  XFilterEvent returns: False
  </code></pre>
  
  <p>The bottom part of the middle button works fine, and returns :</p>
  
  <pre><code>ButtonPress event, serial 37, synthetic NO, window 0x5200001,
  root 0x31d, subw 0x0, time 630137726, (10,171), root:(2801,631),
  state 0x10, button 2, same_screen YES
  
  ButtonRelease event, serial 37, synthetic NO, window 0x5200001,
  root 0x31d, subw 0x0, time 630138960, (10,171), root:(2801,631),
  state 0x210, button 2, same_screen YES
  </code></pre>
  
  <p>I would like the remap the top part the same way as the bottom part, is this possible with xmodmap ?</p>
  
  <p>thanks!</p>
