How it works
Typed words live on the screen, like writing on a foggy window. If the power goes, the fog clears, but saved work stays in a drawer.
Save early, before you write much, and then save again every few minutes.
A file name is like a name tag. A clear name is short and says what the file is. Use letters and spaces.
Choose a folder, so you know where it went and can find it again.
