Most commands can be prefixed by a number, n, that specifies that the command should be repeated n times. For example, 5w means move 5 words forward. Go ahead and give these a try. You'll be told how to get back here. For the searching commands, you have to hit a return to execute the command.
Searches are circular.
The search starts at the current location and proceeds down or up the file. If the end or beginning of file is hit, the search goes to the beginning or end of file and continues from there. If the search makes it back to the location it started from, it stops and lets you know it didn't find anything. Try searching for the string consisting of your first and last names. Note that it is all right to have spaces in your search strings.
