Hello Gretl friends,
In two weeks I'll begin to teach the course "Economic History: Booms and
Busts - Skills for Understanding Crises" This online course was designed to
teach economic history through statistics and the software chosen, of
course, it's Gretl!
The initial level of the students is quite basic, and one of the problems
we have detected is the great majority of them don't have any experience
with statistical software beyond Excel. So, they are used to *undoing*
actions if they make a mistake.
*The question. *As I usually work in gretl with *Hansl* instead of the GUI,
I haven't realized that there is not an "undo" button in the GUI... *Is
there a way to undo an action in Gretl?* Example, if I delete a series,
could I undo this action? if the answer is yes, how?
Thank you in advance and I'll keep you updated regarding the reception of
the course.
Best and happy weekend

There's no "undo" in the gretl GUI other than undoing changes in
text in editable windows such as the script editor.
There is, however, a datafile-backup mechanism: if you overwrite an
existing datafile, the prior version is saved with "~" appended. So
if you don't like changes you made to a datafile you can delete the
new version, rename the backup by removing the "~", and revert to
the prior version.

Maybe it will be beneficial for them to experience in a most practical
way that there are some things in life where mistakes cannot be undone
with a click... and this is relevant to Understanding Crises.
