Sidebar toggle keyboard shortcut

Hi this simple feature would be great for the ones who like working on the keyboard instead of the mouse. Being able to hide and show the toolbar will be really nice because it can make the app look more cleaner(I usually keep sidebar closed at all times). However I have to physically move my mouse to close it every single time i open the app!

If not can you at least add it to the menu bar because then Apple can by itself create shortcuts for all menu bar items?

Thank you!
