Nudging cursor in increments on Cubase 5

Hi guys,

I’ve read that using ctrl with + and - will move my cursor backwards and forward depending on my snap settings, but no matter how hard I try I can’t get it to change from skipping a whole bar, even if I have grid size set to ‘beat’ and Quantize type to 1/4 - it still moves a whole bar. This is the same when using the plus and minus signs next to the time display on the transport bar. Originally it was stuck on moving 1/2 and after tinkering it now moves a whole bar but I can’t figure out how I changed it. I was fiddling with the time display on the transport bar if that’s related at all. Thanks
