What does knit across mean?

I am pretty new to knitting and am still learning things – like how to read a pattern. And I am looking at a pattern for baby booties and one of the rows says knit across - does that mean to just knit the whole row? Or is there some there something else I have to do? Any help would be appreciated. Thanks!

Knit across means just what it sounds like…you just knit across the row w/o doing anything else.
