There are several ways to select a letter or word in puzzle:

• use left/right/down/up arrow on keyboard
• tap/click a square with pen/mouse
• select clue from Across or Down menu
• use select wheel (Zaurus)
• type Tab or Enter key to go to "next" word in current direction

  [default]

  start of next word, i.e. for next clue

  Skip: Word

  next empty square

  with Check: Input

  next incorrect or empty guess

• enter a guess -- next square is selected; if Skip: Letter is on, next empty square in word is selected (with possible wraparound); with Check: Input, next empty or incorrect square in word
• use Home, Page Up, Page Down, End via keyboard for current direction

The current letter highlights in green. [Pref: Select]

The current word and scrollbar and clue (across or down) highlight in cyan. [Pref: Word]

Normally, the current letter/word stays visible after Enter or entering a guess; if Skip: Scroll is turned off, scroll manually as needed.

There are several ways to set the direction to across or down:

• use arrow keys
• drag pen/cursor from a square to another in that direction
• select clue from Across or Down menu
• use select wheel
• toggle Edit: Across menu command

If the across or down clues are clipped in the menus, you can either make the clue font smaller for all clues (Prefs), or select View: Clues to display the current clues (and any cross-references) in a scrollable window.
