Is it just me, or are there just not enough keys to assign to everything usefull? Either way, this is nothing to script, just add the ability to assing multiple keys to an object so you have to push both keys to use that object. Or set up a heirarchy of buttons so you have to push a few buttons in succession to get to what you want. The second may sound bad to some
, but others may not like having to push two buttons at once (think p + z, you'd need both hands) but it will still exponentially raise the amount of hotkeys available. Now, I'm not saying make it so you have to use 2 or more keys, just allow the option.
