Re: Finding Text In Specific Columns

I installed 7.3 and tried your matchadd but it didn't seem to work. I
tried both with [^0] and 0. If one doesn't match the other one should
but I don't see anything highlighted in red.

Running :hi I can see that ErrorMsg is white text on a red background
so it should show up. What am I missing?
