→ Format Vertically Distribute Space

This menu command is used to set the vertical space between the objects your select. The dialog is the same Spacing dialog as in Format -> Align -> Vertically Distribute Space.

You can also choose the distance from 10 to 3000, with an increase of 5. You can also select the "Use as Default" check box to set the default distance.

The standard toolbar also contains an icon for this menu command.
