I always forget to turn the little row counter thingy, anyway, so what I do when I have to remind myself to cable or decrease or whatever is this--I use a little loop of different-colored yarn and keep it at the beginning of the row. At the beginning of row one, I move in down the needle one st so I have my first st, my loop, then the next sts. Each time I come to it I move it up one, so for example, if I am doing the 6th row of the pattern I will move my loop so that there are 6 st to the right of it. If on the 6th row I have to DO something, I do it and then move the loop back to the beginning the next time through. You could have it going for the entire length of your work, I guess, but I've used it for repetitive things. For the rest I count rows afterwards. I started doing this on circs because it doesn't get in the way, but now use it for most things. I hope that makes sense.
