I need a way to trigger a single cell with more than one key, but not using the key range feature. Here's an example of what I'm talking about: Let's say I need a single cell to be triggered by keys C2 and C3, but NOT by any of the 11 keys in between (because they might trigger other cells).
I'm aware that I can just copy the contents of one cell to another, but that's not the answer either because just about every possible cell available in Battery 2 will be in use.
