Cubase 8 Line Tool

I’m currently using Cubase 8 Pro.

and… uh, I don’t think I’ve overlooked anything on the key commands list
but I don’t see the ‘line tool’ written any where under ‘tools’.

I’m pretty sure there was an option to assign a hot-key to the line tool even in Cubase 5.
Was this intentionally removed? Or am I just not seeing it?

I think it’s 9.

I can’t see it. I can’t designate a hotkey to the line tool.
Am I missing something here?
