Choose the settings
For the recorded example, use these settings: Characters to remove: 0123456789.
Each character entered in Characters to remove is matched separately. Matching is case-insensitive, so listing a letter also removes its other case. The value is a character set, not a phrase, regular expression or pattern. Spaces can be included if they should be deleted too.
