Additional Comments
Expander triangle

Use the mouseChar function within a handler to determine which character the mouse is hovering over, in order to take some action based on the current character.

Value:

The mouseCharChunk function returns a chunk expression of the form char charNumber to charNumber of field fieldNumber.

Comments:

The mouseCharChunk function only returns locations in a field. If the mouse pointer is not over a field, the mouseCharChunk function returns empty.

The first and second character numbers in the return value are always identical, unless the mouse is over a field but there is no text under it. In this case, the mouseCharChunk returns a chunk expression of the form char charNumber to charNumber - 1 of field fieldNumber, indicating the start of the mouseLine. For example, if the mouse is over an empty field, the mouseCharChunk returns char 1 to 0 of field fieldNumber.

To get the actual character clicked, use the mouseChar function.
