To improve responsiveness and perceived performance, jEdit executes all buffer input/output tasks asynchronously. When a task such as this is in progress, the status bar displays the number of running tasks.
The >> command displays a window with more detailed status information and progress meters for each task. By default, the is shown in a floating window. This window can be docked using the commands in its top-left corner popup menu; see the section called “Window Docking Layouts”. Tasks can be aborted in this window, however note that aborting a buffer save can result in data loss.
