## Message

```
agent_ui: Simplify thread scrolling with keyboard (#53547)

This change allows using simple navigation keys (PageDown / PageUp /
Ctrl-Home / Ctrl-End) when the message editor is focused, but only if
the cursor is at the beginning/end of the message, where pressing these
keys would normally result in no-op.

One important corollary is that when the cursor is in an empty message,
navigation keys scroll the thread.

We already have this behavior for Up/Down and this change just expands
it for other navigation keys.
