hey so i stupidly spilled some water on my laptop this morning but it wasn't a lot and seemingly nothing happened. then several hours later all of the sudden my delete key and arrow keys are not working. i can only assume this has soemthing to do with the spill. my macbook pro is over 2 years old and i'm pretty sure the warranty is long expired. i definitly can't afford a new one or expensive repairs. is there anything i can do to try to fix it myself? any idea what the problem is? is it an easy or cheap fix? thanks subquestion: is there anyway to change the function of my keys? in other words can i change say one of my shifts or command keys into a new delete key ?
