When using -p mode of git add -p or git stash -p what does each of the letters stand for?

I'm guessing y is yes and n is no. What are the rest?

[y,n,q,a,d,/,K,j,J,g,e,?]

The -p mode means patch, the help for which is hard-ish to find, but if you check git add --help you'll find the following

   patch
       This lets you choose one path out of a status like selection. After choosing the path, it presents the diff between the index and the working tree file and asks you if you want to stage the change of each hunk. You can select one of the following options and type return:
       y - stage this hunk
       n - do not stage this hunk
       q - quit; do not stage this hunk nor any of the remaining ones
       a - stage this hunk and all later hunks in the file
       d - do not stage this hunk nor any of the later hunks in the file
       g - select a hunk to go to
       / - search for a hunk matching the given regex
       j - leave this hunk undecided, see next undecided hunk
       J - leave this hunk undecided, see next hunk
       k - leave this hunk undecided, see previous undecided hunk
       K - leave this hunk undecided, see previous hunk
       s - split the current hunk into smaller hunks
       e - manually edit the current hunk
       ? - print help
