Key baord short cuts

Are there any Key board shortcuts for the side bar that allow you to open and
close them when you have other programs running? It seems like there should
be a logical shortcut like macs have or even the widget programs have, but I
haven’t been able to find it. That’s kind of the point of having the widgets.
If I wanted to manually close an application and then open another to get
info I wouldn’t use a side bar I would just go on the internet and see the
full story. it’s the same amount of steps.
