[1.6.4]Delay Timer and Custom Key Bindings!

[Mecblader]

Hello I am making a mod that has custom levels and those levels determine if the player is a high enough level to use a certain tool and if they are not it displays a chat message. My issue is that the check for that is in a method that is called very often so the chat message gets spammed. I was wondering if there is some sort of timer already built into forge or minecraft that could let me limit the number of times the chat message is displayed to a certain amount like a certain amount of ticks. Also I was wonder if someone could tell me how to add key binding that the player can customize in the controls menu or point me to somewhere I can find out. Thanks in advance!
