So execute normally but remember where you were in the history if you press down. I've always found that a bit weird since if you press up you _lose_ your place. But I grew up in a bash shell before a GAP shell. :-) I'm sure such a thing would be easy by adding another function on top of this patch. FWIW, I think this should go in soon and have another patch to get the GAP behavior, since this has been languishing for quite a while. There should also be a section that basically says, do XYZ to get GAP behavior and WXY to get Magma behavior, etc. -Ivan -- -- To post to this group, send an email to [email protected] To unsubscribe from this group, send an email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
