keyboard control app

[ncamaa]

hello everyone. i need help to find an app that i can use to change the function of a key in my keyboard. what i mean is that when i click for an example on the key "+=" the function will be like clicking on "delete". that's because my 'delete' key stopped working and i don't have the money write now to fix it.
thanks ahead.
