Currently we have "control+click" which was known from pose mode also in animation mode as the keybinding for multi-select nodes.

However, since "control+click" is also "snap to surface" maybe we want to remap that to e.g. shift click or something like that.

Right now you can't select multiple nodes due to that keybinding problem.

In general custom keybindings would be awesome to have at a certain point so that everybody can map those things the way they want to.
