Pressing F1 key

Hi
i havea problem i have this code so if the F1 key is pressed a movieclips ._x changes

if (Key.isDown(113)) {
bg._x = 300
} 

but when i play my flash file in ixplorer and i press F1, ixplorer’s help page pops up :frowning: ,is their some acrionscript command to disable iexplorers key pressings
or maybe java script ,i know you can disable it from within iexplorer but i want my flash to be universal without having to explain to viewers what they must do to get it to work
