This pattern provides a method to access secondary functions of a command button.

Context

Users needs to access a secondary function of a command button.

Forces

The user may not know by looking at the control that a secondary function is available; this function probably must be trained. Functionality to be accessed using this pattern must be well chosen, otherwise interaction might become unclear and confusing.

Solution

The secondary function can be accessed by pressing and holding a command button for longer than a defined timeout, e. g., longer than 1 second.

Sample

Usability Impact

Freeing screen real estate reduces screen clutter and cognitive overhead.

Safety Impact
