I'm back to using a keyboard for the moment my mouse died on me. I am using The num pad for my mouse and the arrow keys for scrolling. Well I was at a page and was going to share it on my wall but I changed my mind. I hit cancel. The arrow keys would not work for scrolling the page anymore. I'm thinking you might be able to make a false facebook page and force a cancel and possibly insert some code into the facebook users session. I'm not sure if I should post this here. I dont know if its a vunribility or not.
