You are now in Editor Mode for the file myfile1.
Add content to the file.
At this point, you can type in some text. Type in your full name, any address, and any phone number number on different lines.
Control the keys for nano.
Note the control menu at the bottom of the nano text editor. The (^) symbol refers to the Ctrl key, so ^X (Exit) refers to simultaneously pressing the Ctrl and X keys. Other common control keys are ^K and ^U for cut and paste operations and ^R for opening a new file. ^W is a control key for finding text in a file.
If you are using nano as your text editor and Internet Explorer or Chrome as your browser, you cannot use Ctrl + O to save your file. This hotkey is used by IE and Chrome to open files. You will have to exit and save as follows: press Ctrl + X (Exit) and at the prompt (Save Modified Buffer), press Y, then Enter. This will save the file and exit the text editor. Mozilla Firefox does not have this issue with Ctrl + O.
Save your modifications and exit.
Press Ctrl + O and press Enter to save your myfile1 file.
