You can navigate to the end not only by scrolling or pressing "Home", but also by clicking the black triangle at the right-top of the chart.
There is no direct way to navigate to a particular period in past. However what you can do is, for instance, if you want to navigate to ticks of 01/07/2011:
- Change period to 1 Day,
- Place a vertical line chart object on the 1st July bar,
- Change period to ticks,
- In Workspace pane find the chart and click on the vertical line object in the chart object tree.
