Minor keymap fixes

Shift+A to add meshes, and Right Mouse to pan the Node Editor were not working.
Everything in Blender was set and exported correctly, but until I opened the keymap in VS Code to manually edit it, the bugs remained.
Thanks to the random poster who pointed out that Blender will sometimes incorrectly format its own keymap, and you might need to type it out yourself to get the expected results.
