Why can't I click any of the tools under "Edit?" I want to merge selected shapefile layers together, but all of the tools under "edit" are greyed out.

Right click on the layer you want to edit in layers panel, and select "Toggle Editting" when the context menu shows. Then the "Edit" menu will be enabled.


You must "Toggle Editing" before any of the edit tools are available.

Fyi if you're trying to merge lines in a kml it won't work, you need to convert to another file type and then convert back (it seems)
