if you have a resistor of, say 100 ohms, you can connect another 100
ohm fixed resistance across its outside terminals (legs) and you will
now have a combined resistance of 50 ohms (they are said to be
connected "in parallel"). the pot will now sweep between zero and
fifty ohms, giving you only half the range but double the sensitivity.
using a smaller resistance will give you even more sensitivity.
if you're interested in the maths: combine two resistances a and b in
parallel to give resistance c
1/c = 1/a + 1/b
hope this helps,
