Keymap in ~/.w3m ignored?

[Thorsten <quintfall@xxxxxxxxxxxxxx>]

Hello list, 
I copied the w3m example keymap from the docs into  ~/.w3m and commented
out all key definitions. Then I changed and uncommented a few keys -
however, nothing changed. 

My .w3m/config has a line:

,-------------------
| keymap_file keymap
`-------------------

that (probably?) refers correctly to the .w3m/keymap in the same folder.  


here an arbitrary excerpt from my keymap file. In the tradition of
xmodmap I assumed that only those keys have to be uncommented that
changed - is that right? 

,----------------------------------
| # keymap        b       PREV_PAGE
| # keymap        c       PEEK
| # keymap        g       BEGIN
| keymap  b       MOVE_LEFT
| # keymap        i       PEEK_IMG
| keymap  n       MOVE_DOWN
| keymap  p       MOVE_UP
| keymap  f       MOVE_RIGHT
| keymap  e       MOUSE_TOGGLE
| keymap  s       SEARCH_NEXT
| # keymap        o       OPTIONS
| # keymap        q       QUIT
| # keymap        r       VERSION
| keymap  m       SELECT_MENU
| # keymap        u       PEEK_LINK
| # keymap        v       VIEW
`----------------------------------

What might be the problem?

cheers
