FR-UI-4 says a gesture with no visible counterpart is a feature only its
author knows about, and the vocabulary the application actually publishes had
two sections in it — the library grid and people. Develop had none. Every one
of its gestures was documented in the comment beside the `TouchArea` that
implements it, which is where the previous sixteen were before this scanner
existed, and unreachable to anybody not reading the source.
Thirteen now carry tags: magnify by pinch or wheel, pan a magnified frame,
fit and 1:1, hold to see the original, sample a neutral, undo and redo, step
through the folder, reset one control, show or hide a mask layer, choose a
group of adjustments, and copy and paste the settings. Each has a pointer and
a touch route, so none of them is keyboard-only.
Three bindings were genuinely missing and are added here rather than merely
described. Ctrl+C and Ctrl+V for the settings clipboard, which the Settings
panel's own comment has claimed existed for as long as the panel has and
nothing bound; and [ and ] to step through the adjustment groups. The groups
are whatever the operation set declares itself to be about, so there are as
many as the pipeline has and no key can name one of them — stepping is the
binding that survives a node being added, and "everything" is part of the
cycle rather than a way out of it.
Two are described and not bound. Resetting a control from the keyboard and
toggling a mask layer from the keyboard both need a notion of which control
or layer has focus, and the generated panel has none — the rows are a model
the repeater rebuilds, and inventing a focus ring for them is a larger change
than a keyboard shortcut. Both are reachable by pointer and by finger, and
the tags say so rather than promising a key that is not there.
