I was able to do this just fine in the previous version of elementary OS. But I've been unable to find a method to do it in Freya.
I want CTRL+ALT+Tto duplicate a tab in Freya with the same directory. So if the current tab is in ~/Workspace/Websites
I can just press the key sequence and it'll open a second tab in ~/Workspace/Websites
as well instead of having to right click on the tab and clicking duplicate.
