I am looking for a program that can copy any selected text to the clipboard automatically. E.g. if I select some text in Safari or Eclipse, it should automatically copy it to the keyboard.
The Google Chrome extension Auto Copy 3.0.3 can do it in Google Chrome.
The application PopClip displays a popover menu which appears when some text is selected in any application but there doesn't seem to be any way to automatically copy it to the keyboard.
