Making what you are looking for as simple as possible is not a bad thing. You never said exactly what you had (the actual bind text) you just said you had each power bound to a key. There are lots of ways to do that so "dumbing" it down is helpful.
Why are you being so combative with people that are trying to help you? Now EVERYONE knows exactly what you had previously and can maybe try and help you get that same functionality. Or maybe they won't since you just seem to want to fight.
Thank you for finally answering a simple question.
Maybe explain exactly how you accomplished this before. I think there's a miscommunication either on how you did this or how what @UberGuy
posted works. Did you try it in game and it doesn't work how you want it to?
The one I used is called Large Concrete & Wood in the Dividers section. There's a few others in there that can work to, depending on what you are trying to accomplish.
You can use floor tiles, you just have to use two, one for each side.
I used something that was easier, but I can't remember what. I'll check when I go on later and let you know.
