+### ↪️ Command Redirection
+
+Sometimes it's useful to redirect the messages generated by a command or function
+to a different view. That can be easily achieved with command redirection.
+
+The redirect API can taken an optional `routes` parameter, which defaults to `{config.redirect}`.
+
+```lua
+-- redirect ":hi"
+require("noice").redirect("hi")
+
+-- redirect some function
+require("noice").redirect(function()
+  print("test")
+end)
+```
+
+Adding the following keymap, will redirect the active cmdline when pressing `<S-Enter>`.
+The cmdline stays open, so you can change the command and execute it again.
+When exiting the cmdline, the popup window will be focused.
+
+```lua
+vim.keymap.set("c", "<S-Enter>", function()
+    require("noice").redirect(vim.fn.getcmdline())
+    end, { desc = "Redirect Cmdline" })
+```
