lynx-dev keystrokes available

[David H]

What keys are still available for potential mapping?

It looks like we still have a lot of capital letter possibilities:
(as of dev16)

Letter    lowercase     uppercase     control
  A       ADD_BOOKMARK  --            HOME
  B       PREV_PAGE     --            PREV_PAGE
  C       COMMENT       --            <reserved>
  D       DOWNLOAD      --            ABORT
  E       EDIT          ELGOTO        END
  F       DIRED_MENU    --            NEXT_PAGE    # DIRED_MENU only in DIRED
  G       GOTO          ECGOTO        --
  H       PREV_DOC      HELP          HISTORY      # Different if vi keys off
  I       INDEX         --            NEXT_LINK
  J       NEXT_LINK     JUMP          ACTIVATE     # Different if vi keys off
  K       PREV_LINK     KEYMAP        COOKIE_JAR   # Different if vi keys off
  L       ACTIVATE      LIST          REFRESH      # Different if vi keys off
  M       MAIN_MENU     --            ACTIVATE
  N       NEXT          --            DOWN_TWO
  O       OPTIONS       --            <reserved>
  P       PRINT         --            UP_TWO
  Q       QUIT          ABORT         <reserved>
  R       DEL_BOOKMARK  --            RELOAD
  S       INDEX_SEARCH  --            <reserved>
  T       TAG_LINK      --            TRACE_TOGGLE # TAG_LINK only in DIRED
  U       PREV_DOC      --            --
  V       VIEW_BOOKMARK VLINKS        SWITCH_DTD
  W       --            --            REFRESH
  X       NOCACHE       --            --
  Y       --            --            <reserved>
  Z       INTERRUPT     --            <reserved>

As for other punctuation, there appear to be at least a few still
available:

    (space)             NEXT_PAGE
  ! (exclamation)       SHELL
  " (quote)             SOFT_DQUOTES

  $ (dollar)            --
  % (percent)           --
  & (ampersand)         --
  ' (apostrophe)        HISTORICAL
  ( (open paren)        UP_HALF
  ) (close paren)       DOWN_HALF
  * (asterisk)          IMAGE_TOGGLE
  + (plus)              NEXT_PAGE

  - (minus)             PREV_PAGE
  . (period)            EXTERN
  / (f slash)           WHEREIS
...
  : (colon)             --
  ; (semicolon)         TRACE_LOG
  < (less than)         UP_LINK
  = (equals)            INFO
  > (greater than)      DOWN_LINK        control
  ? (question)          HELP             =======
  @ (at)                RAW_TOGGLE       <reserved, NUL>
...                              
  [ (open bracket)      INLINE_TOGGLE    <reserved, ESC>
  \ (backslash)         SOURCE           <reserved>
  ] (close bracket)     HEAD             --
  ^ (caret)             --               --
  _ (underline)         CLEAR_AUTH       <reserved?>
  ` (backquote)         MINIMAL
...
  { (open brace)        --
  | (vertical bar)      --
  } (close brace)       --
  ~ (tilde)             --

All in all (unless I'm missing some information about control characters),
the following 34 keys are available:

A B C D F ^G I M N O P R S T U ^U w W X ^X y Y Z $ % & : ^] ^ ^^ { | } ~
