Is your feature request related to a problem? Please describe.
I am usually deeply in a nested structure and I can't find stuff on the disk.

Describe the solution you'd like
I was searching for a button eg. the Home-Key to jump into my users home directory to start the search there.

Describe alternatives you've considered
I read about shortcuts, but the docs are not good enough for a 5min fix.

Additional context
I like this project so far, please add more docs and explain better why the service is needed.

Problem is the Home key could be used for other things:

1. going top of the list, as in some other list based applications
2. going to the beginning of the input, which is always focused
3. going to ~

I've chosen 2.

I'm open to suggestions regarding a shortcut to go to ~.

What if there was a shortcut on the ~-key?
Or when one enters :~ it could jump to to?

Or Alt + Home?

OK, here's what I'll do (should be done by tomorrow):

1. define a few more internal verbs, among them :focus_root and :focus_user_home
2. allow configuration to map trigger keys to verbs

It means you'll be able to add this to config.toml:

[[verbs]]
invocation = "root"
key = "F9"
execution = ":focus_root"

[[verbs]]
invocation = "home"
key = "ctrl-H"
execution = ":focus_user_home"

In this example, ctrl-H sends to your home, and F9 sends to /.

I don't know if there will also be a default mapping for those actions as none seems obvious.
