+This command creates a new shell and begin at this path.
+
+## Examples
+
+```shell
+/home/foobar> cat user.json
+{
+	"Name": "Peter",
+	"Age": 30,
+	"Telephone": 88204828,
+	"Country": "Singapore"
+}
+/home/foobar> enter user.json
+/> ls
+━━━━━━━┯━━━━━┯━━━━━━━━━━━┯━━━━━━━━━━━
+ Name  │ Age │ Telephone │ Country

+ Peter │  30 │  88204828 │ Singapore
+━━━━━━━┷━━━━━┷━━━━━━━━━━━┷━━━━━━━━━━━
+/> exit
+/home/foobar>
+```
+
+It also provides the ability to work with multiple directories at the same time. This command will allow you to create a new "shell" and enter it at the specified path. You can toggle between this new shell and the original shell with the `p` (for previous) and `n` (for next), allowing you to navigate around a ring buffer of shells. Once you're done with a shell, you can `exit` it and remove it from the ring buffer.

+```shell
+/> enter /tmp
+/tmp> enter /usr
+/usr> enter /bin
+/bin> enter /opt
+/opt> p
+/bin> p
+/usr> p
+/tmp> p
+/> n
+/tmp>
+```
