+# Command-line tips & tricks
+
+Typing long commands over and over again can quickly get tiresome
+
+--
+
+Thankfully, modern command interpreters provide handy shortcuts to make life
+easier
+- please get used to them as early as you can!
+
+--
+
+The **up/down arrows** allow you recall previously typed commands, which you can
+then edit and modify as required (using the left/right arrows)
+- very useful when you have a single typo on a long command
+
+--
+
+The **TAB key** asks the shell to complete the current word if it has enough
+information to do so. 
+- for example, typing `cd Doc`, then pressing the `TAB` will complete the
+  command to `cd Documents` 
+  - *provided* there is a `Documents` folder at that location
+  - *and* there are no other folders that start with `Doc`

+# Create a folder on the command-line

+- navigate to the location where you want to create the folder, for example:
+  ```bash

+

+- use the `mkdir` command to create the desired folder:

+- navigate to this folder, and create a subfolder for this first example:

+  cd OOP/
