Reference field icon On forms, the reference icon ( in UI16/UI15, in UI11) appears by populated reference fields. Pointing to the icon opens a read-only preview of the referenced record. Figure 1. Referenced record preview on a form The preview closes when you move the cursor unless you hold the Shift key (or the Alt key on some UK keyboards) while moving the cursor. Clicking the reference icon prompts you to save or discard your changes, then navigates to the referenced record. Note: The reference icon behaves differently in lists. For more information, see List fields. Configure the fields in the pop-up for a reference iconYou can use the sys_popup form view to configure the fields in the pop-up that appears when pointing to a reference icon. If the table has no sys_popup view, the pop-up uses the default view.Configure the pop-up delay for a reference iconWhen you point to the reference icon in a form or a v2 list, the reference pop-up appears after a configurable period of time.Configure pop-ups on read-only fieldsReference pop-ups and click-throughs are hidden by default when a client script, UI policy, or ACL makes the field read-only. The ability to see or click through to the target record does not depend on whether the reference field is writable. You can change the read-only setting.
