Hello! Everyone!

I come to you again, because I will need a system of item that will not use the system HotKeys, basically I would like us to use a specific key to the use of the object and another for the choice of the object ..
I tried various code modifiers and so on, to the point where I delete everything ... So, I did another but it is not operational ....



I also have another request ...
I would like the user to hold a "CTRL" for example ..
And "X" buttons (Previous) and "C" (Next) Object ..
Can also display two previous and two following?

Thanks.....
[P.S : If ever there is a problem of understanding I go edit my post ..]

Nobody?
