The main area contains a list of all the current processes in the Lisp image. Properties of each process are shown in the columns Name , Priority and Status .
If you have many processes running, you can use the filter area to only list processes containing a given string. For example, if you enter "Running" in the filter area, and click on 
then only processes that have the word "Running" in their description will be shown.
The processes displayed in the main area can be sorted by clicking the relevant button above each column. For example, to sort all listed processes by process priority, click on the Priority title button.
