+ or +	Keys same as cursor up and down except that it additionally marks all the rows in focus
+ or +	Keys same as page up and down except that it additionally marks all the rows in focus
+	Run the correlation process within the database for the transaction in focus
+	Expand all child transactions of the transaction in focus
+	Collapse all child transactions of the transaction in focus
	key expands the complete sub-tree of the item in focus
+	Highlight max duration of all child transactions of the transaction in focus (See Focused item context menu for details)

Header row

The header row of the tree view supports the same functionality as the header row for the table view. For general information how to resize or arrange the columns please read the appriopriate header row section. Some additional transaction attributes are supported by the tree view which are described in the following section.

Transaction attribute context menu

"The transaction attribute context menu" depicts the context menu which is used to show or hide transaction attribute columns. A check mark indicates that the appropriate transaction attribute is shown in the table as an own column.

In addition to the transaction attributes described in the table view Transaction attribute context menu the following transaction attributes are supported by the tree view:

Duration %: displays the relative duration of the transaction according to the root transaction in percent.
Net duration: displays the net duration of the transaction without any time spent for waiting of finished child transactions.

The three red highlighted rows shows the transaction with biggest net durations within that transaction tree. See Tree analysis preferences for more details on highlighting transactions within a tree. The yellow highlighted durations indicates that these transactions are expensive within their transaction tree since they have a net duration of more than 33% percent of the overall duration of the root transaction. The color and percentage can be configured in the Tree analysis preferences .
