remember.el defines the following interactive functions:
Remember an arbitrary piece of data. With a prefix, it will use the region as initial.
If called from within the remember buffer, beg and end are ignored, and the entire buffer will be remembered. If called from any other buffer, that region, plus any context information specific to that region, will be remembered.
Remember the contents of the current clipboard. This is most useful for remembering things from Netscape or other X Windows applications.
