Anyone knows the mnemonics to remember where each key moves the cursor to?

I can't find the documentation telling why those keys were chosen, I remember it
was something like:

Code:
          ???
           k
           | North
       /-------\
       |       |
??? h--|  you  |--l ???
  West |       | East
       \-------/
           | South
           j
     (Lake?) Java
             ^
Any ideas about the other 3?
