In OpenWindows, mouse button 2 was referred to as the ADJUST button-because it was used to highlight the text to the right of a position selected by mouse button one. CDE uses mouse button 2 as a useful text duplication button, which is used to duplicate, or make copies of, selected text.
Duplication is faster than copy and paste or drag-and-drop, especially when you want to quickly copy a long file path into File Manager, or when you want to copy commands in a terminal window. The contents of the clipboard are unaffected when duplicating.
Select the required text by holding down mouse button 1 and dragging the cursor over it.
Release mouse button 1.
Point the mouse at the location to which you wish to duplicate the text, and click mouse button 2.
The text is copied to the new location without removing it from its original location.
(Optional), Repeat step 2 and duplicate the text in other locations.
