You can start a new file by clicking the 
button. Alternatively, you can click the rightmost tab ＋ on the files tab strip or press "Ctrl+N". The new file is loaded in a new tab on the right. A default name is assigned automatically in the form "new n", where n is an incrementing counter — for example "new 1", "new 2", and so on.
