I asked a question in the (La)TeX stack exchange and it was recommended to me that I see whether I could get an answer here. The question can be found here.
The basic question is this: can I tell Vim to interpret the 'paragraph' text object differently? Now paragraphs are defines as blocks of text separated by a blank line, but I want to change this to blocks of text separated by a line that contains a percentage symbol (%), which is th comment symbol in LateX, i.e. that Vim understand that:
This is a paragraph % This is another paragraph
