Creating mouse shortcuts (xbindkeys and xte help)

I want the “search” button on my mouse to be a middle click.

In my .xbindkeysrc file I have

"xte 'keydown Control_L' 'mouseclick 1' 'keyup Control_L'"
#  m:225

but it still just selects the google search bar on firefox.

Using xev, it shows

KeyRelease event, serial 34, synthetic NO, window 0x2600001,
    root 0xb4, subw 0x0, time 166414200, (1135,637), root:(1139,660),
    state 0x10, keycode 225 (keysym 0x1008ff1b, XF86Search), same_screen YES,
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

that means its seen as a keyboard button 225 right?

I tried doing something like

"konqueror"
m:225

to test it, but nothing. Something is overwriting its function. In Configure Desktop > Keyboard & Mouse > shortcut stuff, and didn’t see the search button used anywhere.

fixed it thanks to https://bbs.archlinux.org/viewtopic.php?pid=461074#p461074
