FeatReq: add button or command to disable/enable screen selection

Please add an option or a command to set in the toolbar that can switch off and on the selection on the screen.
RATIONALE: Apps using buttons and scrollbars need the touch interaction to be not impeded by the selection process. Almost all the times when the user want to press a button or drag a scrollbar he ends just selecting the characters on the screen instead of activating the touch bindings.

SOLUTION: Using TUI apps like those made with Textual or Prompt.Toolkit requires the user to disable/enable the selection of the screen at will from the toolbar. The user can still select the text via keyboard with shift+arrow keys, in a purely non touch way.
