Search text for occurrences of the Find value and replace
each of them. The 'wrap around' value controls the start
point for searching. If wrap isn't set, then the searching
starts at the first occurrence after the current selection;
if wrap is set, the replacement starts at the first line.
The replacement is always done top-to-bottom in the text.

Text is highlighted via the 'hit' tag and the marked
section is brought into view.
The colors from the 'hit' tag aren't currently shown
when the text is displayed. This is due to the 'sel'
tag being added first, so the colors in the 'sel'
config are seen instead of the colors for 'hit'.
