// wl_qp_quickPickWalk v1.0
//
// This script will setup pickwalking on your rigs
//
// To use, load an object into the Home button, then select the object
// you want to walk to from that object, and click the direction button.
// Do this for all your rig's control objects.
//
// !!! The toggle button will modify arrow/cursor hotkeys!!!
// The toggle button will allow you to use the arrow keys for pickwalking. It toggles between
// Maya's default heirachy pickwalking and this scripts hotkey commands
//
// If you want to give your animators the option of toggling the cursor hotkeys
// make a button with wl_qp_hotkeysShelfButton as the command
//
// Drop it into your scripts folder which is usually:
// My Documents\maya\[version]\prefs\scripts
//
// Make a button with wl_quickPickwalk as the command
//
// Any bugs, let me know.
