problem revit

[alessio94]

Good evening, I have a prblemino with revit, today while working on a school project by mistake I closed the vertical bar where you go in the various pages (the one on the left under the bar of ownership, to undo us where there were the various plants, prospects etc.) and I no longer know how to reopen it, you know how to open it? ?
Thank you very much
