One of the new additions to Chapters (get it now in v1.0.8) is additional extended keyboard keys. In addition to creating bullet lists and timestamping your entries, you can quickly navigate by word or character using the arrow keys.
Tapping the word-skip key will cause the cursor to jump by one word in the desired direction. You can fix or change a word without having to tap the screen and zero in on the specific location.
Additionally, you can position the cursor by character using the character skip buttons.
These buttons make writing on your iPad easier and I hope you like having them.
