Add .resetAll() method

[sindresorhus]

Which would reset all the shortcuts in extension KeyboardShortcuts.Name.

This cannot be done until Swift supports static key paths. We could potentially do something with Mirror today, but it's not important enough to do such a hacky workaround.

Feature needed!

I set plenty of Shortcuts using their name. But some times these names gone, and I cannot find a way to reset them.

In the current documentation, I find two methods: reset(names: ..) which must use the shortcut name to reset and removeAllHandlers() which just remove handlers except for the shortcuts in UserDefault...

The current workaround is to follow this to get all the Name's and pass them to .reset(names: …).
