When working with a trace, think of the selected event (highlighted green by default) as your cursor. Most of your actions depend on the position of this event. The selected event is the event that you last clicked with the left mouse button (unless scrolling has moved that event off the trace, in which case the program selects another event).
The following keys can help you navigate the trace:
You can locate specific events in one of two ways:
Scrolling the trace
Scrolling horizontally across the trace is much more complex than simply moving the cursor
along the trace lines. There are three mechanisms for scrolling: slide bar, trace line
arrows, and scroll buttons. As you scroll, the trace is continually refreshed to reflect
precedence relationships to the selected event. This is done so that as many events as
possible can be shown on the screen at one time.
Tagging an event
Tagging adds a bookmark-type identifier to an event so that you can return directly to it
at any time.
Finding an event
The Find Event dialog box enables you to locate a specific event by its object, method,
and server host names, or, if defined, by its event tag.
