SUMMARY
Currently you need to have a cell selected (indicated by highlight) in order to add / remove a keyframe for this cell. Once you have selected a cell, (currently by clicking) you can navigate your cell selection horizontally using the next & previous frame keybinds, or scrolling.

However if you now wish to add and remove keyframes for another line, there is no way of moving your current selection up or down a line without having to manually click a cell in that line.

STEPS TO REPRODUCE
1. Make multiple layers and have them displayed in the timeline.
2. Bind next/ previous frame AND next / previous layer controls.
3. Select a cell by clicking then use your next and previous frame keybinds
4. Now use the next and previous layer keybinds

OBSERVED RESULT
The selection moves horizontally with next / previous frame functionaliy.
But does not change with next / previous layer functionaliy.

EXPECTED RESULT
The selection moves horizontally with next / previous frame functionaliy.
The selection moves vertically with next / previous layer functionaliy.
