Deleting large numbers of paths

From Fs_wiki

One other thing I have been trying to do in Tunnel, is to import part of a sketch into another sketch. I have not found an easy way to do this. Is there a way to select part of a sketch (i.e. a subset) and import only that?

Is there a way to select multiple paths to delete them all? It is a pain to have to select one at a time and them click delete for each one. Even allowing them to be deleted with the Delete key on the keyboard would help.

The first request would be quite difficult to make an interface for. I'd need to know more of why you are doing it. For the second I have made a "todelete" subset. Please see Subsets_and_styles Goatchurch 22:56, 10 October 2006 (BST)

Footleg 13:52, 11 October 2006 (BST) - That helps a great deal. The actual use case here is that I have a fairly complete drawing of the cave in Tunnel based on some old data. Now that I have some better data I restarted the drawing from scratch, but wanted to import selected parts of the original sketch into the new one. This is why I asked if it was possible to import a specific subset. However a reasonable work around is to copy the original sketch, delete all the bits I don't want, and then import what is left into my new sketch. This is now possible as I can more easily delete large portions of the old sketch using the 'todelete' subset.
