in steps : in the schematic sheet hold on any component press F to edit component footprint press select many libs will appear now i am searching for pj-202a package how to find it simply ?
I don't have the kicad libs in use nor installed, but I would try 'barrel' or 'jack' or '2.0mm' and then compare the footprint you get with the ones in the datasheet.Also, be aware there is a footprint repo browser integrated into PCBnew (button with book/magnifying glass on it) that will allow you to search visually as well and speed things up in case you don't have the correct search terms.
in cvpcb there is a field in the top to help you search, in the library browser you should know where it exists.
I have the same interrogation.
I see no field to make a search and ctrl+F does not work.
I have seen nothing in the documentation.
Is this bugfix commit related?
don't think so.It seems not to be a bug, just not implemented.
The *.pdf documents created by @felixq, and linked from the Forum threads at https://forum.kicad.info/t/full-footprint-library-lists-ideally-in-ascii/3334/6 and https://forum.kicad.info/t/full-footprint-library-lists-ideally-in-ascii/3334/8 provide a handy reference. They may be out of date by now, but at least you have a starting point for where to look for footprints.
