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.
