Why not define a Ctrl-". This would fill a field with one date higher than the field above it.
I do a fair amount of data entry that involves date data into a database table. I can use the Ctrl-' function to add to the field the data in the same field directly above it. This is great. But I have to enter a lot of records with dates, and the new record is for a different date, usually the next date on the calendar. So if there was a function Ctrl-", I would be able to directly add the next day to this record when compared to the record above it. For example if Record 12 has a date of 6/1/2020, I could go to Record 12 and in the same field type Ctrl-", and 6/2/2020 would be entered into that record in Record 13.
I should have said "I could go to Record 13 in the same field, type Ctrl-", and 6/2/2020 would be entered into that record.
