FX Tab Disappeared

Hi can someone please help me locating FX tab, it has disappeared from my timeline… I am trying to hit Control + Tab but not happening.

I thought that you were looking for the small FX button at the top right of the Timeline but I’m not so sure. That button will make the Timeline FX ribbon appear, but the Ctrl-Tab shortcut should still work the it is hidden. If this is not what you are looking for it would help if you could post a screenshot showing your problem.

do you need to have the Sequence open?
