View > Right Panel (view.rightPanel, F8) hides the right panel and shows the one that was
there again (Edit when nothing was remembered; Crop, Remove, Masking and Red Eye end when
hidden and come back as Edit). View > Hide All Panels (view.allPanels, Shift+Tab) hides the
left sidebar, the right panel, the Presets column and the filmstrip; the next press brings
back exactly what was shown, so a panel that was already hidden stays hidden. Showing any
panel by hand while they are hidden makes the snapshot stale: the next Shift+Tab hides again
instead of resurrecting old state. Both commands take an optional show / hide parameter and
are checked in the View menu while they apply. The top bar and tool strip stay.
Shift+Tab is also egui's "focus previous widget", set when the pass begins and without
consuming the key; with nothing focused it focused the loupe. The shortcut consumes the key
and cancels the traversal. In a focused text field neither key is a shortcut, and Shift+Tab
keeps moving focus as before. On a Mac keyboard F8 is Play/Pause unless fn is held or
"Use F1, F2, ... as standard function keys" is on.
Docs: KEYC-PANELS is partial (Tab, T, F5 and solo remain; F6 / F7 are in PR #1078), KEYC-HELP
is done (F1), KEYC-RATING's missing list drops the already implemented [ ] keys, two View
menu rows are added, gap 28 shrinks, and the parity summary is refreshed with
cargo xtask parity --write (it was already stale on main).
The native menu leaves Shift+Tab to egui (no accelerator, so the macOS menu shows no key hint) and
the native_menu accelerator test lists it with the other keys egui handles.
