The viewer.nudge shortcuts bailed out unless Composition, Viewer or Timeline
had focus, so with any other panel focused the arrows silently did nothing.
After Effects nudges from almost anywhere; only the Project panel owns the
arrows for its own keyboard navigation. Typing, dialogs, menus and selected
mask vertices still keep the keys.
Tests: arrow nudge from Effect Controls, no nudge from Project, Shift+arrow
10x, time untouched, click-row path.
Previous / Next Frame also answer to Cmd+Left / Cmd+Right Arrow, and Back / Forward
10 Frames to Cmd+Shift+Left / Right, next to the Page keys (After Effects' second
default keys). A command spec can now list several default shortcuts
(`alt_shortcuts`, `cmd!(…, ["PageDown", "Cmd+ArrowRight"], …)`); menus and tooltips
keep showing the first.
