Keyboard navigation

In Lighttable-previews it is possible to use mouse-click to select an image and shift+mouse-click to select a range and ctrl+mouse-click to select non-adjacent images.

In Darkroom-filmstrip. It is possible to do the same but to preview an image requires a double click

In neither context does the keyboard allow equivalent behaviour. In Darkroom, the arrows control panning - I suggest easier navigation would be to use the mouse-wheel to zoom in and out, using the mouse cursor position as the zoom centre reference point

In Lighttable-previews, I would expect Shift+left or right arrow to extend or contract the selected images. Arrow to move to a new potential selection and Ctrl+space or Ctrl+enter adds that image to the selection

In Darktable-filmstrip, I would expect Shift+left or right arrow to extend or contract the selected images, so settings can be applied in batch. The ability to use a key to increment or decrement the current image displayed seems to be missing and I think is a major omission. Certainly, if you implement the mouse wheel zoom I suggested above , it would free up the arrow keys for this capability, though on-adjacent selection may prove more difficult where the arrow keys are committed as suggested but a bit of collective brainstorming/prototyping is likely to generate a workable solution.

Additional context

Start by reviewing keyboard and selection handling in Lighttable-previews and Darkroom-filmstrip, then compare it with the existing mouse interactions. Clarify which navigation, range-selection, non-adjacent-selection, zoom, and preview behaviors are in scope. Done means the agreed keyboard interactions work consistently in both contexts, with tests or reproducible checks covering selection and image navigation.
