When the feature is turned on, dragging across the page displays an icon.
Hovering over the icon shows a floating area containing the selected text, from which various button operations can be performed.
If no text is selected in the floating area, the function will execute the full text.
When the text in the floating area is selected, the function is executed only in that part of the text.
Full button extracts all text on the page.
