As #2059 has been readily accepted, we have not had the time to discuss the documentation.
This PR, like #2059, wire keybindings to private methods. Please, let me know how to best document this behaviour.

Before moving forward with more 3-key chord supports, we need to first figure out how to make Get/Set-PSReadLineKeyHandler support chords with more than 2 keys. Today, _chordDispatchTable is a 2-level dictionary, and hence it only really supports 2-key chords. Get/Set-PSReadLineKeyHandler are implemented under that assumption.

By looking at #2059 again, I think I merged it a little too prematurely :)
Today, we have two 3-key chords built-in:

• <d,g,g> -- implemented by having g mapped to ViDBChord in the DTable with a DGTable that maps the second g to the handler.
• <d,w,i> --implemented by #2059.

There are 2 concerns here:

1. Their implementation should be consistent in the way how the 3rd level dictionary is stored.
2. Changes to VI key binding data structure are needed to make Get/Set-PSReadLineKeyHandler to support chords with 3 keys (are we stopping at 3-key chords for VI mode here? maybe we should and not support chords with more than 3 keys).

I think we should first resolve the above concerns before adding more text object commands.

It seems GetBeginningOfLogicalLinePos and GetEndOfLogicalLinePos shoudl be put in StringBuilderLinewiseExtensions instead.

Added by mistake? It doesn't seem to be needed by the code changes in this file.

BTW, the <d,i> shows up in the results of Get-PSReadLineKeyHandler:

User defined functions
======================

Key   Function          Description
---   --------          -----------
<d,i> ChordViTextObject ChordViTextObject

Two problems here:

1. ChordViTextObject is not put in GetDisplayGrouping(string function), so it's displayed as User defined functions.
2. The chord <d,i> is incomplete -- users will try using it but observe no result (or unexpected result).

It's the same for <d,g>:

Miscellaneous functions
=======================

Key        Function          Description
---        --------          -----------
<d,g>      ViDGChord         ViDGChord

@daxian-dbw I have published #3853 to address your feedback, re-working #2059 in the process.
I’m happy for this current PR to be closed as I will be able to move the code forward in a better shape if #3853 is accepted.
