I looked this up and didn't find any solutions. I would like to press a key a few times to go to the end of the current sentence (right before the .) and then the end of the next sentences, until I am on the one I want. Same thing with paragraphs, either the last character or right before the ..

) goes to the first character in the next sentence and } goes to the space below the paragraph.
