Terminal sessions have a default name, "Terminal 1", "Terminal 2", and so on. Rename the current terminal via the Rename Terminal command on the drop-down. For example, renaming "Terminal 3" to "Remote Session" in the previous example gives this:. Thus, in your workflow, you can create multiple terminals and give them meaningful names to simplify navigation. A collection of named terminals, or "terminal set", is generally associated with an RStudio project.

If a single-line was sent to the terminal the cursor will advance automatically to the next line, allowing single-stepping. This will also work on Windows, but no check is done that the shell-type loaded in the active terminal session matches the commands being sent.

This button does not appear in Windows. If there are busy terminal sessions, trying to exit RStudio or any other operation that will stop the current R session will give a warning.

Finally, if the terminal feature it not useful to your workflow, you can remove the tab altogether by clicking the [x] on the Terminal tab itself. The terminal buffer keeps the last lines of output when running non-full-screen terminal programs.

You can scroll through this buffer using the scrollbars via the mouse or a mouse-wheel if your system supports it. Full-screen programs typically have their own built-in buffers and navigation conventions.
