Why does delete key produce dots?

The delete key may produce dots due to a specific setting or feature in the software or application being used. For instance, in some text editors or Word processing programs, pressing delete while certain formatting options are enabled can result in visual indicators like dots, which often represent spaces or formatting marks. Additionally, it could be a keyboard shortcut or an unintended function activated by a combination of keys. Checking the application's settings or preferences may help resolve the issue.
