Add a hotkey that moves to the next/previous opid that is different
The o/shift+o hotkeys move to the opid that is the same. It would be useful to have a key that moved to the next message that has a different opid. This would match with how the next/previous file hotkeys work.
Sounds useful to have, in general my own logs tend to change opid many times on any one page. Just occasionally there is a stream of one source that I might want to jump past. Would they operate from top line or from bottom line (so to next off screen item)? For me I think the latter option would be more useful of the two. I had not spotted the o/O command and it is useful to jump along the output of one process without needing to filter etc (plus I get contextual info when not filtered). On macOS there are many processes that get renewed (new pid) frequently. For those it would be useful to move by process name rather than pid (pid may be much short lived)... p/P would sit well next to o/O....
