Select Options|Word Wrap from the menu to toggle word wrapping on or off. By default, word wrap takes place at the right edge of the EditPad window. If you want the text to wrap at a certain number of characters, use the drop-down menu of the word wrap button on the toolbar. You can select one of a few commonly used line lengths, or define your own.
Note that "word wrap" is a file type specific setting in EditPad. If you change the setting through the Options menu or the toolbar, it is applied to the active file only. If you create a new file or open an existing one, the setting made in File Type Editor Options for the type of file you are creating or opening, will be used. Also, when you use File|Save As, and you save the file with a new extension, then the setting for the current file will change into what you specified in File Types Preferences for the file type that corresponds with the file's new extension.
Word wrapping is only used in text mode. In hexadecimal mode, use Options|Record Size.
