How to copy / paste text in gitk

Problem:
How to copy / paste text from git?
Text select and Ctrl-C + Ctrl-V does not paste the copied text. And there is no Edit / Copy / Paste menu item.

Solution:
gitk supports the normal X clipboard, thus

1. Select text, Ctrl-C to copy.
2. Paste text into X terminal window used to start gitk ! It does paste here.
3. Next do copy / paste again to any of your editor / tool.

Voila !
