The Interaction tools can be quite useful for "zeroing in" on an interesting part of an event, such as the showers in the endcap in the above screenshot.
Projections
Projections are default views for the display.
Access the available projections by right-clicking and going to the Projection submenu.
The ParallelProjection submenu contains the most useful projections for our purposes.
Try selecting Projection -> ParallelProjection -> ZY.
This is a "side view".
The XY projection is a front or beam view, which is the same as Action -> Reset.
