Checking which text is under the pointer with Lingo

Lingo can detect which text component in a text or field cast member is currently under the mouse pointer.

Use Lingo that applies to text and field cast members as follows:

| To detect which character in a text or field cast member is under the pointer, use the `pointToChar()` function. See `pointToChar()`.
| To detect which item in a text or field cast member is under the pointer, use the `pointToItem()` function. See `pointToItem()`.
| To detect which word in a text or field cast member is under the pointer, use the `pointToWord()` function. See `pointToWord()`.
| To detect which paragraph in a text or field cast member is under the pointer, use the `pointToParagraph()` function. See `pointToParagraph()`.

Use Lingo that applies only to text cast members as follows:

| To detect whether a specific point is in a hyperlink within a text cast member and is under the pointer, use the `pointInHyperlink()` function. See `pointInHyperlink()`.

Use Lingo that applies only to field cast members as follows:

| To detect which line in a field is under the pointer, use the `mouseLine` function. See `mouseLine`.
| To detect which word in a field is under the pointer, use the `mouseWord` function. See `mouseWord`.
