- /*
- * The CutSelection class works like a normal TextSelection except that
- * we maintain seperate variables for the visible start and end of the
- * selection. This is handy when you want to save a block of characters,
- * but when you install: the selection, you want the insertion point at
- * the end. Use this class when the characters to be saved don't correspond
- * directly to the characters to be shown in the selection.
