I think Koha should add "Circulation Codes", kind of like Follett Destiny has. %C167I for "Reset", etc So for example, to use "reset", when a user scans their library card, and then a couple books, while still highlighting the book barcode field, if Koha detects they enter "%C167I" instead of a valid barcode, it goes back to /cgi-bin/koha/circ/circulation.pl (not circulation-home.pl). This would make "Touchless" checkouts super easy!
I think it would be good for this: %RESET% - Redirect back to /cgi-bin/koha/circ/circulation.pl Here's what the follett ones are: http://destinyhelp192en.fsc.follett.com/Content/Resources/Images/Barcodes/10-19-2016%2011-17-00.png
