key bound to place block

[thegunmaster]

For something i have been working on i will need to know which control is used to place blocks with, so the control that would be right click by default.  But i can't figure out how to acces this data, this might be because i am just really new to modding. Or it is just really dificult. So does anybody know how to get which key is asigned to this?
