The frame editor

Seven modes, each with its own tools and its own canvas. Shift+1..7 switches mode; the tool hotkeys below are global, so the same letter picks the same tool in every mode that has it.

Generated from web/lib/editor/registry.ts, which is what builds the tool strip - so every tool listed here is a tool that exists.

The two keys worth learning first

Enter confirms the frame and moves to the next one. A accepts the selection (in Review mode) or accepts everything (elsewhere). Most of a review session is those two keys.
