Adding an idea based on this thread:

https://community.sdl.com/product-groups/translationproductivity/f/studio/5404/navigation-move-to-next-previous-segment/103277#103277

The idea is well explained here by Timothy Barton:

In the list of keyboard shortcuts, there's one called "Move to next segment". It does not say "Move to next unconfirmed segment". So one would expect it to move to the very next segment, irrespective of its status. It does not. It moves to the next unconfirmed segment. Even if you don't create a feature enabling us to move to the next segment, I think at the very least you should rename "Move to next segment" as "Move to next unconfirmed segment".

At the very least the description should be correct because it doesn't behave as it says.  But I think this should be fixed so you can navigate through the segments with a single keyboard action.
