Workflow to open new Terminal tab in currently opened window

[Arnaud]

Is there any way to have a workflow that opens a new tab in the currently opened window? Even if the window is not focused.

I'm struggling to do that.
Thanks for your help.

AppleScript is your friend. Unfortunately, Terminal's scripting support sucks, so you have to simulate keyboard shortcuts instead:
 
tell application "System Events"

    tell application process "Terminal"

        set frontmost to true

        keystroke "t" using command down

    end tell

end tell

 
On my machine, that opens a new Terminal window if none is open, and creates a new tab in the front window otherwise.
