[DOCS] Interactive mode docs missing `/copy` write-to-file shortcut (`w` key)

Documentation Type

Missing documentation (feature not documented)

Documentation Location

https://code.claude.com/docs/en/interactive-mode

Section/Topic

/copy command behavior and picker actions.

Current Documentation

The /copy row currently says:

| /copy | Copy the last assistant response to clipboard. When code blocks are present, shows an interactive picker to select individual blocks or the full response |

There is no mention of writing the focused selection directly to a file.

What's Wrong or Missing?

Release v2.1.72 added a w key action in the /copy picker to write the focused selection directly to a file (bypassing clipboard flow, useful for SSH/remote sessions).

Current docs only describe clipboard behavior, so users cannot discover this non-clipboard export path from the command reference.

Suggested Improvement

Update the /copy command docs to include picker actions, including:

1. Existing clipboard copy behavior.
2. w shortcut to write the focused selection directly to a file.
3. A short note about when file output is useful (for example, remote terminals where clipboard integration is unavailable).

Impact

Medium - Makes feature difficult to understand
