+Some other commands that also work on files in the working tree and/or
+in the index can take `--staged` and/or `--worktree`.
+
+* `--staged` is exactly like `--cached`, which is used to ask a
+ command to only work on the index, not the working tree.
+
+* `--worktree` is the opposite, to ask a command to work on the
+ working tree only, not the index.
+
+* The two options can be specified together to ask a command to work
+ on both the index and the working tree.
