Quite a simple but annoying one at times.
Ctrl + Click on most nodes adds it to selection.
Ctrl + Click on a node with code editor opens the editor.
Since editor can already be opened with right click as well, can nodes with editor follow consistent behaviour?
oui. actually that extra option to open an editor is only needed for dynamic plugins that also have a gui (rare case). those open the gui by default on right-click. and now you can use Shift + Click to open the editor and Ctrl + Click to toggle selection. see latest alphas.
