Where can users view field descriptions in Looker?

Users can view field descriptions in Looker as a hover-over in the Field Picker. This feature enhances user experience by providing immediate context and information about each field without requiring users to navigate away from their current task or view. When a user hovers over a field name in the Field Picker, they can see any associated description, which helps them to understand the data being presented and make informed choices when building reports, dashboards, or exploring data.

The other options do not provide the same level of direct access to field descriptions. For instance, the dashboard layout does not inherently include descriptions directly next to fields, making it less user-friendly for field data exploration. A separate Help menu could be useful for general guidance or instructions but is not specifically designed to provide real-time context for individual fields. Command line interactions would not typically offer a direct means for users to access field descriptions in a user-friendly manner, as it is more focused on data manipulation than on user interface elements.
