Description

Issue:

Before editing an important file, it is usually good practice first to make a copy.

In Thunar, copying a file within a given folder can only be performed through copy + paste. Copy + paste, however, overwrites the clipboard which may contain valuable information still to be used later.

The Nemo file manager and the Nautilus file manager, amongst others, also allow CTRL + drag to copy a file within any given folder. CTRL + drag does not write to the clipboard. (Thunar thus far only facilitates CTRL + drag between two different folders.)

Solution:

Add CTRL + drag functionality to copy files within a folder to Thunar.

Version: 1.6.3
