Swap function

Introduce a clipboard functionality that enables a text swap operation. This feature should allow a user to copy text from Location A and then select text in Location B. Upon pasting the text from Location A into Location B, the previously selected text from Location B should be automatically copied to the clipboard. This process effectively swaps the text between the two locations, streamlining the task of exchanging text segments without the need for multiple copy-paste actions. This feature would enhance productivity and efficiency in text editing and manipulation tasks.
