Intel® Trace Analyzer 9.1 Update 2 User and Reference Guide
In addition to the menu entries and shortcuts, there are two more ways to navigate the time interval in Intel® Trace Analyzer:
Use the scroll bar found below the timelines
Use the mouse to zoom into a time interval
Similar to the keystrokes, these operations manipulate the zoom stack.
To move the View by a quarter of a screen to a selected direction, click the arrow buttons of the scroll bar. To move the View by one entire screen, click into the bar. Both actions push the new interval onto the zoom stack.
To use the mouse for zooming, left-click the timeline (even clicking into the Time Scale works) and select the region of the new time interval, keeping the left mouse button pressed. On releasing the left mouse button this new interval is pushed onto the zoom stack.
