What I mean is actually the ability to sort library by calling “sort order definition file”, such that I can switch several sort schemes instantaneously. I often change the sort of my library, like Custom 1>Year>Journal, Journal>Author, or Simply by Record number back and forth.
Now, I know your suggestion I can display record number by changing “Display fields” in the Preference, and click the field bar on top to sort by the record number. Problem is, I usually display my custom 1 to custom 4 fields, along with Journal/Author/Title/Year, to look all of my custom input (like ranking, my own review notes, etc). So, going and changing Preference every time is not really convenient. Probably, real problem is that Endnote can show only 8 fields at the same time. I always want to see at least 10 fields at the same time. Then I can display record number all the time.
Thanks.
