I don't think moveMap.bind() creates a proper, customizable keybind for Blockland. Use this method instead:
if(!$CustomBindsMapped)
{
$remapDivision[$remapCount] = "category here";
$remapName[$remapCount] = "keybind name";
$remapCmd[$remapCount] = "function name";
$remapCount++;
$CustomBindsMapped = 1;
}
