Keyboard Options

• If you are using a device without a physical keyboard, the on-screen keyboard is numeric (0 = auto-pencil marks).
• 'use default' ➞ use the default, non-numeric keyboard (0 ≠ auto-pencil marks).
• 'disable 0' ➞ disable the 0 for auto-pencil marks.
• 'add / remove' ➞ add / remove characters, entering the same character again will remove it (by removing all duplicates and sorting).

Pencil Marks

• Pencil marks are squares with more than one digit or letter.
• They are similar to those you might use with pen and paper.
• A square might contain more pencil marks than can be seen.
