Vim: move around quickly inside of long line

• You can use $, 0, and ^ to move to line endpoints and then use w and b. Also, adding a numeric argument to w and b can accelerate the process, so using 6w instead of just w can put you about to where ou need to be.
• Using f and t to move to individual characters will help also. (I use this typically with punctuation. If, for example, I have four sentences on one long line 2f. will go to the end of the second sentence)
• Using the ( and ) keys are an alternative way to navigate entire sentences.
• Splitting out long lines into multiple lines (manually, or with set tw=72 [or 80]) can make editing them simpler. You can always join them later with J.
• Something I just discovered, you can move up and down one displayed line by using gj and gk. That way, you can treat your one wrapped line as multiple lines.
