 For example, if you navigate to your root directory by running the command `cd`, if you're on a Mac, you will probably have 2 folders within your root directory named "Downloads" and "Documents" (these are standard folder names created by default in most systems, although you may have renamed them, or your system may be different). With these, or longer folder names, it can sometimes become cumbersome to type the full folder name. Instead, you can start typing the command and folder name such as `cd Dow` and then press **tab** to autocomplete. Like magic, the command line should complete the statement correctly to be `cd Downloads`. (Note: this will not work if you have another folder that begins with "Dow". Similarly, if you just typed `cd D` or `cd Do` followed by **tab**, the command line will not autocomplete, as the selection is not unique, because **D** or **Do** could both refer to either **Documents** or **Downloads**. Also note that these commands are case sensitive, and folder capitalization much be matched exactly.
