Relevant commands are available from Tool Tabs located along the right side of the display.  The location is user-defined using the VX Configuration Form.  They are also dockable panels that can be dragged to any location using the handles provided.  The default Tool Bar will change depending on the VX level that is currently active (e.g., Part, Sketch, Drawing Sheet or CAM). 
 

Select a tab to display a set of tools.  Left-click a top icon to select it. If an icon has an indicator  to the right, right-click to display an additional submenu.  When you select an icon it becomes the new default menu icon.  The figure below illustrate this functionality.  Each Tool Tab is configured to provide some (but not all) of the available tools for a given application (e.g., features, surfacing, mold design, assembly, etc.).  Additional commands are available from the pull down menus.
