[DOCS] Message selector docs missing new "Summarize from here" action (v2.1.32)

Documentation Type

Missing documentation (feature not documented)

Section/Topic

Message selector / rewind documentation for the new "Summarize from here" capability.

Current Documentation

The keybindings page currently lists only navigation/select actions for MessageSelector:

messageSelector:up, messageSelector:down, messageSelector:top, messageSelector:bottom, messageSelector:select

Checkpointing docs describe rewind options as:

"Conversation only", "Code only", or "Both code and conversation"

No docs mention a "Summarize from here" action.

What's Wrong or Missing?

Claude Code changelog v2.1.32 says:

Added "Summarize from here" to the message selector, allowing partial conversation summarization.

This new action is missing from user-facing docs, so users do not know:

1. Where to access it.
2. What scope it summarizes.
3. How it differs from /compact or rewind options.
4. Whether there is a keyboard shortcut/action name for keybindings.

Suggested Improvement

Update keybindings, checkpointing, and interactive-mode docs to include:

1. A dedicated Summarize from here explanation in rewind/message selector flows.
2. Associated action name and default keybinding (if available).
3. A short behavior matrix comparing /compact vs Summarize from here vs rewind.
4. A minimal example showing when partial summarization is useful.

Impact

Medium - Makes feature difficult to understand
