\textsf{Gretl} provides keyboard shortcuts for various commands. Some of
these are standard and are indicated in the menus; for example
\texttt{Ctrl-s} in the main window saves the current dataset, as
indicated under the \textsf{File} menu. Others are specific to
\textsf{gretl} and do not appear in the menus; these are documented
below.
