On a laptop I prefer to adjust module sliders with the keyboard instead of using the touch-pad and clicking. Better control.
But giving focus to a slider is quite a pain, can only be done with the mouse: rightclick twice.
For example: I open the module Contrast, Brightness, Saturation by clicking on it.
Somehow you would expect that keyboard focus for arrow keys is then automatically set on the first slider/dropdown etc. It isn't.
Then you expect something like tab to move to the next to input (like on the web). Well Tab is not available, but CTRL Tab could be a viable alternative.
And there is no visual feedback which slider has keyboard focus. Ouch!
I'm sure I'm missing something, but how is focusing sliders supposed to work with the keyboard in Darktable?
