The dialog for automatic text replacement is accessible through menu Preferences / Text replacement.
Bibledit can replace certain text with other text for printing and export. For example, whenever the text << occurs, it can be replaced with an opening quotation mark. And >> can be replaced with a closing quotation mark.
These texts, and their replacements, can be set through the dialog.
First thing to do is to enable this feature in the dialog.
Next thing is to enter all texts and their replacements. To set a text, click once on the text where it says "Set new text (or replacement) here", then click once again, type the new text, and press Enter.
To remove a text and its replacement, just erase it.
Press Ok to save the values.
Note. When exporting to USFM, no replacement is done.
