An example on how to implement navigation as suggested in below idea.
https://community.qlik.com/t5/Qlik-Sense-Enterprise-Ideas/Select-next-previous-value-action-for-Navi...
The idea is to select one value in a field and then be able to move selection to next or previous value in the field by a button action. In this example two variable as used to catch what the previous and next values would be based on current selection.
The value order in this example is controlled by a index field, to allow controlling the preferred sort order. The buttons are setup with action "Select a value in a field", where the selection simply is made towards the previous or next value.
