 - `<Enter>` - Open the selected file
 - `<C-d>` - Open the selected file and run `Jdiff`
 
+If Snacks is not enabled, `picker.status()` falls back to `vim.ui.select()`, where selecting an entry simply opens the chosen file.

+### File history picker (Snacks.nvim)
+
+`picker.file_history()` shows the current buffer's revision history.
+
+When Snacks is enabled, you get a fuzzy picker with a diff preview for each revision. Selecting an entry edits that revision with `jj edit <rev> --ignore-immutable` and refreshes changed buffers.
+
+If Snacks is not enabled, `picker.file_history()` falls back to `vim.ui.select()` with the same revision list. Selecting an entry performs the same edit action and buffer refresh, but without the Snacks preview UI.
+
 ### Conflict picker (Snacks.nvim)
 
 `picker.conflict()` opens a picker for `jj log -r 'conflicts()'`, so you can resolve conflicted revisions without first navigating to them in the log buffer.
