Unable to write \l into the terminal -

In the learn-relational-databases-by-building-a-mario-database lesson i am unable to type \l into the command line.

When i try to copy/paste it i get “Unable to read from the browser’s clipboard.”

Anyone got any recommendations?

You have not told us why you cannot type the backslash character?
If your keyboard doesn’t have it you can switch to an English United States language keyboard in your computer so you can find it and type it in.

For copy and paste, if you are copying from CodeRoad, select the text and right click over it then choose Copy. After that place your mouse into the terminal area and click once to place the cursor at the prompt then press SHIFT-INSERT.
