Worker supports some basic drag'n'drop (DND) which currently only works inside Worker. In normal drag'n'drop systems like GNOME or KDE it's possible to drag some file to a different location by holding down the left mouse button. Because Worker uses a different selection scheme for the file list view, the drag'n'drop is activate slightly differently but it gives more control in my opinion.
To start the DND select the entry and hold down the left mousebutton just as in normal DND systems. The drag is started by pressing the right mouse button (while still holding the left mouse button). You can now move the entry to the final destination and release the left mouse button but you can also abort the drag'n'drop operation by pressing the right mouse button again.
The actual action executed when dropping the entry depends on the file type of the entry. Don't expect that the entry is copied to the destination directory. Directories for example are viewed if they are dropped at a list view, archives will be extracted. Each file type has an own configuration section about drag'n'drop actions.
Besides the unusual activation there are some additional limitations:
Describe the VFS
Changing sortmode using hotkeys
Doubleclick on unknown files (executing commands of different filetype, use vfs)
