// ============================================================
// THE shortcut table. One source of truth for both views of the shortcuts overlay: the list
// (Shell/ShortcutsOverlay.cs) and the visual keyboard (Shell/KeyboardMapOverlay.cs).
//
// This was two hand maintained tables until 1.7.5 and they had drifted apart: Home and End read
// "first / last page" on the list but carried separate captions on the map, Alt+M was missing
// from the map entirely, and Ctrl+B was documented as bold in one section and as the sidebar in
// another while the code did neither consistently. Deriving both views from one array means a
// binding cannot be described two ways, and ShortcutTableTests holds that.
//
// Deliberately free of WPF and of MainWindow, so KillerPDF.Tests can link the file the way it
// links OcrCatalog.cs. Anything that needs a Brush or a Control belongs in the overlay files.

//
// Ctrl and Alt are in here because German writes Strg. The gesture phrases are whole
// tokens rather than assembled from "Wheel" plus "on" plus "view", because word order in
