Select all
If you want to select all items in the elements list at once, you can click All at the bottom of the page.
When you click All or press CTRL+A, the root displays an All selected status.
You can click the Close button to cancel the selection.
While Select all is active, clicking in the list to select one or more specific items cancels the All selected status.
Note  
*Select all does not act as a filter when navigating to the next level. It works like selecting the root node and then navigating to the next level. For some TSIs, such as Work Orders , you need to specify a filter to be able to navigate to the next level.
