Allow <TAB> to cycle through options instead of select

[coxley]

I'd love to move over to mcfly from fzf, but the keyboard shortcuts are doing me in. I don't have arrow keys that are ergonomically accessible, so <TAB> is much preferred.

To make this possible, we'd probably need config options for the main actions. Such as changing what <ENTER> does. (I'd prefer that to do what <TAB> does today)

+1 for this. binding the other keys to F1, F2, etc conflict with Tilda.

the ability to configure these in a .dotfile would be nice

Not related to the actual topic of the issue, but perhaps it helps you personally. If you're used to vim you can make mcfly use j and k to move through the different elements with the vim key scheme (it does change some other things though)

Having inaccessible arrow keys feels like it should be a reasonably common issue so maybe this would best be addressed with a third key scheme designed with that in mind?

Now that a config is merged in (https://github.com/cantino/mcfly/pull/405), I'd be open to a PR to change this.
