you have enabled filters, use F6 to turn them of.
Use F5 to switch the filter bar on/off and play with it -this is really useful.
so it represent the fact I cannot select entities cause I have some active filter, right?
But how come did it appears? what's its function?
Filters are a good selection tool, and may be used in many cases not only in the sketch.
Drawings, Assemblies, multibody part...
