Nav Screen Showing Padlock IconHave you ever broken your ambush by accidentally clicking somewhere or pressing a movement key? Maybe you have a cat that likes walking on the keyboard causing you to end up in open space without your knowledge!

Usually this is a mere inconvenience but depending on where you end up, it could prove deadly (hopefully not so for your cat).

This userscript prevents you from moving off your current tile either by a keypress or mouse click. A padlock shows beside the Commands section of the navigation screen to show whether movement is unlocked (the initial state after installation) or locked. Just click the padlock to toggle between the unlocked and locked states.
