Currently to go to the next or previous difference, you have to use Ctrl+Alt+Up/Down and Ctrl+Alt+Home/End .
PS: These button dont actually work on my fresh Debian 13 setup, but maybe this is an issue on my side (Ctrl+End, Ctrl+Home does work)
I think that button combination is really hard to reach on a standard keyboard. I think the following combination might be much easier:
Replace Ctrl+Alt+Up with g
Replace Ctrl+Alt+Down with j
Replace Ctrl+Alt+Home with ge (e stands for edge, so i think it's intuitive)
Replace Ctrl+Alt+End with je
Above combinations are bit inspired from vim, but i think they are easier to use.
I dont think this will conflict with the Find window because that input field has to be focused in order to type things there
