You can use a particular Editor tool solely as a buffers list.
To do this, set an Editor tool to be non-reusable by switching off the option
Tools > Customize > Reuse Editor
. Then select the
tab or press
This Editor tool will continue to display the buffers list and will not be re-used by operations which want to display a buffer, or list definitions, and so on. Other Editor tools will be used, and created as necessary, for those operations.
