Forum: Inkscape I'm struggling with node selection

Hi!
That's my first try with Inkscape and I think I've broken it.
Every time I select 2+ nodes with the "Edit path by nodes" tool the
critter add 1 other node between the 2 selected.
See the little wmv attached :)

I know...I've clicked something not supposed to be clicked :°D

Thank in advance for you help :)
