5.2.7 Navigating Directories

5.2.7 Navigating Directories

Often when you are cleaning up directories, you're moving files between them, organizing subdirectories, and the like. This naturally involves a lot of moving among directories.

To move to the parent directory of the one you're in, press ^. To move to the next directory in the buffer, press >; pressing <, not surprisingly, moves you to the previous directory in the buffer.

Sometimes it's more convenient to edit a directory and its subdirectories in the same buffer. To insert a subdirectory in the current Dired buffer, move to it and press i. Emacs inserts the subdirectory at the end of the buffer. If you insert more subdirectories in this fashion, they will appear in alphabetical order at the end of the buffer.

As you can see, much of your file maintenance and cleanup can be done easily from within Dired. Table 5-2 summarizes Dired commands, some of which we haven't fully discussed. There's more to learn about Dired,[29] but now that you know the basics, you can experiment on your own.
