Well - I don't think you are actually *missing* one, as I think it was 
not there in the first place :-)

There usually is space for two of those rubber parts under the RETURN 
key, but there is only one mounted there - so if you place two of them 
under the RETURN key, you miss one elsewhere :-)

btw: if you have disassembled the whole keyboard, it might be a good idea 
to clean the gold contacts and the inner part of the rubber parts (with 
the small, round piece of conductive rubber) with a cotton-wool-tip and 
some ethanol or isopropanol alcohol (use at least 95% pure alcohol, and 
no aceton or other sharper solvents) - you get a much better keyboard 
reaction, just as if it was new :-)
