+### Shortcut audit (#110)
+
+Checked against Microsoft's published "Keyboard shortcuts in Excel" (Windows and Mac tables,
+2026-10-11). Alt key-tip sequences are tracked separately (#33). Bindings live in
+`crates/ui-egui/src/grid.rs` (navigation, editing keys), `ribbon::shortcut` (Ctrl/Cmd letters),
+`keymap.rs` (everything added in #110, with a `lookup` table that tests cover) and
+`formula_bar.rs` (keys while editing). "Ctrl" means Cmd on a Mac unless the Mac column says
+otherwise. Number-format and border keys match the physical key (Ctrl+Shift+4, wherever `$` is).
