Easy switch between brush and eraser

[Piotr Jasielski]

Does anyone know how to set a one key switch between those two? 

Just like the "x" key for switching colors.

hold E and erase, let go E and it goes back to previous tool, in this case your brush, would this help? Not sure how to make a shortcut like the switch colors, perhaps with a script. I know adobe has some sort of scripteditor program, maybe you can do something with that.

Oh yes that's great! Thanks a lot!
