It honestly couldn't be easier. We were thinking of how design the easiest, most user-friendly way, to create a new shortcut. And this is what we came up to.
If you like what you are seeing at any particular moment, you can always simply click the button Add a Shortcut.
After this, you can decide whether you want to rewrite an existing shortcut, or create a brand new one, in which case you pick a name for it. And that's it.
Shortcuts are actually just clever combinations of all three types of filters and your existing projects.
And, as you've probably already guessed, removing shortcuts is even easier. Just right-click on the shortcut you want to remove and pick Delete from the drop-down menu.
