Tutorials
The User Guide is the starting point for learning rev. Its chapters cover a first saved file, editing, buffers and panes, search, file browsing, preferences, native completion and optional modal editing.
For a specific task, use the how-to guides. Exact controls and settings belong in the reference.
Git
The independent Git path starts with a local repository, then reviews saved changes, selected commits and history.
Org mode
The Org mode guide starts directly with an Org file and continues through outlines, tasks, agendas and tables. It is separate from the everyday editor learning path.
