Quick navigation for bug occurrences

[gmile]

Is your feature request related to a problem? Please describe.
On the error page, when browsing multiple occurrences of the error to better understand the problem, today I need to make several actions:

1. click on the "occurrences" dropdown,
2. point cursor at the item from the dropdown,
3. click on the item

This is a tiny bit of hassle. It would be much more convenient if there existed a way to browse occurrences with fewer actions, for example by clicking some kind of "Next occurrence" / "Previous occurrence" buttons or links.

Describe the solution you'd like
Have a "Next occurrence" / "Previous occurrence" links available on the error page.

Describe alternatives you've considered
Have keyboard hotkeys available to go to previous and next occurrence.

Additional context
None.

I think that this makes sense and could potentially help with #138.
