In the fields sidebar, which character denotes alphanumeric field values?

In Splunk's fields sidebar, alphanumeric field values are denoted by the percentage sign (%). This symbol is used to represent values that can include both letters and numbers, indicating that the field can contain a combination of characters, such as alphanumeric strings, rather than being limited to numeric or specific types of values. The presence of the percentage sign is significant, as it helps users quickly identify which fields can contain a wider range of data types. Understanding this notation is important for effectively navigating and utilizing the Splunk interface, particularly when analyzing logs or other datasets that include varied field types.
