[v2][auto-prompt] Output panel has no cursor controls

### Describe the feature

Currently, the output panel has fewer shortkeys than the doc panel (see below):


In particular, the output panel has no defined keys for moving the cursor other than searching and finding.

This doesn't make much sense as it may be crucial to navigate in the output panel, especially if the output object is long and doesn't fit in a single page.

The output panel should have the same navigation options as the doc panel.

EDIT: it seems to be possible to move up and down one line in the output panel with the _Ctrl-P_ and _Ctrl-N_ key bindings, which are, however, not documented.

### Use Case

This is useful for inspecting the output object when it exceeds the terminal height and thus gets truncated.
