When I do any kind of point editing with Inkscape, I will have an object (A) and delete one of the points hoping to get C, but instead I get B. I understand why this happens, it's so curves can be made more optimal, but very often I don't want my handle types to change. It is tedious enough making sure points are no-handles corners without Inkscape continually messing them up. Is there a different way I can remove anchor points that will retain the handles of its connected anchors?
I just found this very extensive list of hotkeys.
Backspace or Del : delete selected node(s)
Ctrl+Backspace or Ctrl+Del : delete without preserving shape
Toggling the checkbox in eazimmerman's answer reverses these commands.
