I have to check all the elements on a layer and I'm looking for an easy way to go through all of them. One option would be to open the attribute table and just always click on the next line and then "move to selection". I would prefer an option where I just click on an arrow or use a shortcut and QGIS just jumps to the next element, so that I don't have to be aware of not missing a line and just needing half the amount of clicks. Is there anything like that in QGIS?
I just found the selectnext Plugin http://plugins.qgis.org/plugins/selenext that does exactly what I want.
EDIT: Selenext seems to be missing in the repository lately. It can be installed by downloading it from https://github.com/geodrinx/selenext unzipping the file and copying the folder to ~/.qgis2/python/plugins (Linux only). After a restart of QGIS it will be available.
