I have a number of polygon attribute tables with columns that I want to update with new information. Is there a way of (relatively) quickly editing info in attribute tables in QGIS eg such as using Control C and V such as in MapInfo. Currently seem to need to double click/right click/copy, move to cell, double click/right click/paste each individual cell I want to change - would like something simple rather than going down the field calculator, filter, etc route. With points no problem; I usually throw them out to Excel, edit and then bring back in again. Any pointers appreciated.
If your editing situation is conditional you may use a CASE expression within field calculator:
CASE expression A conditional expression that can be used to evaluate multiple expressions and return a result.
CASE WHEN condition THEN result [ ...n ] [ ELSE result ] END
CASE WHEN "mycolumn" = 'A' THEN 'Letter A' WHEN "mycolumn" = 'B' THEN 'Letter B' ELSE "mycolumn" END
This should at least eliminate the need to perform selections and filters before running calculations.
