When you press Enter after a line of text, the system inserts a double space. If you wish your next line to be single-spaced, press Shift + Enter at the end of a line of text.

To change a double spaced line to single spacing:

• Click at the end of the first line.
• Press Delete on the keyboard.
  The lower line of text will move up and share the line above - that's ok.
• Press Shift + Enter to apply a single space return.
• Save.
