Translation of blinzeln

I will usually use the most usual sense of the term, and not the more sophisticated ones and I think you will understand what I wanted to say. In any case we should review all words every two days or so.
I've also looked at the interface, and found it a good idea to include the colloquial option. Would it be very complicated to add the most important regional check box, like Spain, South America or Central America?
My Spanish is weak, and I need to improve it here. But it is very difficult because I have many other things to do. I must take care of my family and my friends and have no time for Spanish.
