Note about text editors in Element K: All text editor tasks in this lab are shown using the nano text editor but you are also free to use the vi text editor as an option if you know the more complex command hierarchy. If you are using nano as your text editor and Internet Explorer or Chrome as your browser, you cannot use O to save your file. This hot key is used by IE and Chrome to open files. You will have to exit and save as follows: press X (exit), and at the Save Modified Buffer prompt, press Y and then Enter. This will save the file and exit the text editor. Mozilla Firefox does not have this issue with O.
