- Join selected nodes
- Break path at selected nodes
- Join selected endnodes with a new segment
- Delete segment between two non-endpoint nodes
Do they exist?
Creating this question FINALLY answered it for myself!
See https://inkscape.org/doc/keys092.html. I was always searching for shortcuts for "Break path at selected nodes", but in the above document it is listed under the description "Break selected node(s)". Creating this question made me look for the other actions as well, some of which are listed by their correct description.
Hope this can be of use to others!
The keyboard and mouse reference says:
Shift + J join selected nodes This requires that exactly two end nodes within the path be selected. You can lock the position of one of the two joined nodes by hovering mouse over it.
Alt + J join selected end nodes with new segment
Shift + B break selected node(s) After break, only one of each two new nodes is selected. May apply to more than one node.
Alt + Backspace delete segment between pairs of adjacent selected nodes
I just tested these on 0.92 and they work as expected.
