A simple method to move between patch hunks is first to search for the beginning of the patch marker
in a unified diff
/^@@Enter
in a context diff
/^\*\{15}Enter
and then to move to the next hunk by repeating the search with
n (or multiple hunks at a time, e.g. 3n)
To move backwards by hunks use
N (or e.g. 4N)
If you know all the hunk numbers you need to see, e.g. the 11th and 24th hunk, you can first use the amount prefix search Hugh suggested: 11/^@@Enter and after that move to 24th hunk either by calculating always from the top: gg24n or by direct forward advance: 13n (hunk #24 is 13 hunks ahead from the 11th).
