After 17 commits of feature work the standalone window had a lot of
hidden keyboard shortcuts (Cmd+Z, Cmd+C/V/D, Delete, Alt+drag, etc.)
that no user could discover. This adds:
- 'Shortcuts (?)' toolbar button next to Export Visio.
- '?' key (or Shift+/) toggles the overlay; Esc closes it.
- A read-only modal that lists every canvas-relevant shortcut in
a 2-column table (Action / Shortcut) with <kbd> tags for the
key combos, styled to look like physical keys.
- Click on the dimmed overlay backdrop also closes it.
- Reuses the existing .fc-modal fade + scale-in animation.
The overlay sits inside #fc-left so it overlays the canvas, not the
side panel. Hidden by default via the HTML hidden attribute.
Implementation: btnHelp / shortcutsModal / shortcutsOverlay /
shortcutsClose are added to the bundle's els bag. A small
showShortcutsOverlay / hideShortcutsOverlay pair toggles their
.hidden. The keydown handler gets two new branches at the top:
- Esc: close the overlay if open.
- ? (computed from ev.key === '?' or 'Shift+/', no modifier
keys held): toggle the overlay.
Both branches return early so the existing Cmd+Z / Cmd+C / etc.
handlers below them still work.
Tests: 3 new (1386 total) covering the toolbar toggle, the
? + Esc keyboard flow, and that every shortcut the user can
trigger is listed in the modal.
