[FEATURE] Allow customization of keybindings about cursive

[gyscos]

Hi, and thanks for the report!

The usual solution for shortcuts and custom input management is to handle it externally, from a wrapper view.
You should be able to use an OnEventView to intercept some or all events, and process them based on some shared ruleset you can maintain and change at will.

In your case, you may be interested in on_pre_event_inner, so that you can:

• Have access to the event before it is given to the wrapped view, so you can change its behaviour.
• Have access to the view, so you can forward "fake" events (for example send 10 times the "down arrow" event).

Now I agree that this relies on the view you want to control to expose what you need - if something is currently private and not available, we can absolutely consider making it public!

Yeah we're using this wherever possible, but for some cases this doesn't work (mainly with the scrolling)

Exactly that is my "problem" with the ScrollView. In order to implement some vim-keybindings (and in the future, more of such custom actions) we need to be able to access the underlying scrolling ...

EDIT: Oh wow, while researching this, I discovered that the Scroller trait is public, meaning that we can get mutable access to the scroll::Core of the ScrollView. And the methods there are all public. So, my issue with the scrolling has fixed itself (if I've just read the documentation more thoroughly...).

Before continuing with this issue, I'll research a bit more to find out if the issue I'm having is already "fixed".

Anyways, thanks a lot already!
