is there a key stroke to select the “next” object in the scene, similar to RMB on another object in object mode ?

“Next” could mean the object below the selected one in the outliner but is really does not matter which one it is as long all objects are cycled through.

I would like to automate repetitive tasks. One way is to use python scripting. When scripting is not appropriate/possible/straightforward, it is also possible to fake a series of key strokes by an external program such as xvkbd on linux. This works somewhat but to make it more useful it would be great to have a key stroke which select the “next” object.

Any comments/tips ?
