Learn English – Abbreviation for current

I am looking for an abbreviation for the word "current" to match the similar abbreviation "prev" for "previous" (it is being used specifically in the context of a sequence of items: previous –> current –> next). I'm considering "cur" and "curr", but the former brings to my mind the slur and the latter, as far as I can tell, isn't in widespread usage. I'm also aware of "cnt" occasionally being used, but it doesn't really match the style of abbreviation in "prev", and it can be ambiguous as to whether it abbreviates "current" or "count". Am I just being paranoid about "cur"?
