my_txt.scroll
Description
Property; defines the vertical position of text in a text field. The
directing users to a specific paragraph in a long passage, or creating scrolling text fields. This
property can be retrieved and modified.
The units of horizontal scrolling are pixels, while the units of vertical scrolling are lines.
Horizontal scrolling is measured in pixels because most fonts you typically use are proportionally
spaced; meaning, the characters can have different widths. Flash performs vertical scrolling by line
because users usually want to see a line of text in its entirety, as opposed to seeing a partial line.
Even if there are multiple fonts on a line, the height of the line adjusts to fit the largest font in use.
