+pyTermTk_ include a clipboard wrapper :class:`~TermTk.TTkGui.clipboard.TTkClipboard`, around any of the following libraries:
+
+- `copykitten <https://github.com/klavionik/copykitten>`_ - Robust, dependency-free way to use the system clipboard in Python.
+- `pyperclip <https://github.com/asweigart/pyperclip>`_ - Python module for cross-platform clipboard functions.
+- `pyperclip3 <https://pypi.org/project/pyperclip3>`_ / `pyclip <https://github.com/spyoungtech/pyclip>`_  - Cross-platform Clipboard module for Python with binary support.
+- `clipboard <https://github.com/terryyin/clipboard>`_  - A cross platform clipboard operation library of Python. Works for Windows, Mac and Linux.

+
+The basic pyTermTk_ does not include any of those clipboard managers.
+An internal implementation whitin the scope of the app itself is still available.
+
+If any of the previous listed clipboard managers are installed, pyTermTk_ is able to automatically detect and use them.
+
+i.e.
+
+.. code:: bash
+
+    # Assuming no clipboard managers are installed
+    # you can still copy/paste between editors in this session
+    # but no text is copied to/from the system clipboard
+    python3 demo/showcase/textedit.py
+
+    # if pyperclip is installed,
+    # pyTermTk defaults the clipboard manager to this tool
+    # any copy/paste is synced with the system clipboard
+    # it is possible to copy/paste from/to an external editor
+    pip install pyperclip
+    python3 demo/showcase/textedit.py
+
+-----
+Usage
+-----
+
+Once initialized the clipboard manager, 2 apis are provided that can be used to access the clipboard (:class:`~TermTk.TTkGui.clipboard.TTkClipboard.setText`, :class:`~TermTk.TTkGui.clipboard.TTkClipboard.text`)
+
+    .. code:: python
+
+        from TermTk import TTkClipboard
+
+        # Initialize the clipboard manager
+        clipboard = TTkClipboard()
+
+        # Push some text to the clipboard
+        clipboard.setText("Example")
+
+        # Get the text from the clipboard
+        text = clipboard.text()
