"Edit book: File list: Allow using Ctrl+Left/Right to move an item to top/bottom of the list"
I think that should be
… using Ctrl+Shift+Left/Right to….
IMO: Because they are not configurable (not suggesting they should be) the Ctrl+Shift+↑, ↓, Home/←, and End/→ shortcuts should be discoverable.
Suggest a Move fly-out in the File Browser context menu.
First (Ctrl+Shift+Home/←)
Up (Ctrl+Shift+↑)
Down (Ctrl+Shift+↓)
Last (Ctrl+Shift+End/→)
Precedent - Rich text/Comments editor context menu has fixed shortcuts shown in its context menu.
