> Is there a keyboard shortcut for Relink to Copied?

A verb for relinking a clone to the copied exists [2] and can be used for assigning a shortcut key. Add the following line to your keymap file [1] and adjust the key and modifiers as needed:

  <bind key="d" modifiers="Ctrl,Alt" action="EditRelinkClone" display="true" />

[1] user keymap file:
     ~/.config/keys/default.xml
    system keymap file:
     /usr/share/inkscape/keys/default.xml

[2] available verbs for clones (0.47, 047+devel):
- EditClone: Create a clone (a copy linked to the original)
             of selected object
- EditUnlinkClone: Cut the selected clones' links to the originals,
                   turning them into standalone objects
- EditRelinkClone: Relink the selected clones to the object currently
                   on the clipboard
- EditCloneSelectOriginal: Select the object to which the selected
                           clone is linked
