You can specify which punctuation signs require a space before, and which require a space after.
Use the Character map buttons to add punctuation signs to the corresponding edit box.
You can modify the contents of these edit boxes in the same way as you modify contents of ordinary edit boxes. For example, to delete a punctuation sign, select it, then press the Del key.
If the Allow double space between sentences box is checked, Atlantis will not remove double spaces between sentences.
A non-breaking space might be inserted by the AutoCorrect at times instead of an ordinary space so that line wrapping won't separate a word from its associated punctuation mark. If the Use nonbreaking spaces box is checked, Atlantis will insert nonbreaking spaces when required. Otherwise ordinary spaces will be used.
