MarkMyWords Texteditor uses Mac OSXs internal textsystem. This means, almost all features you know from other applications, that uses the internal textsystem (for example Apples Texteditor) are available in MarkMyWords too. Those special features can be activated via the contextual menu. Under OSX Snow Leopard the new feature Text Replacement is also available.
Beneath the texteditor are the current charactercount and wordcount displayed.
Automatic save
While working on text, MarkMyWords continually saves the written text in the background. For the case of a computer crash or a power failure MarkMyWords brings up the unsaved documents on next start.
Save your work in a regular manner, backup your documents on external medias and / or use Apples Time Machine for a regular backup because in case of a harddrive crash even an automatic save wouldn't help.
