At the current version of krunner, there is no "convenient" method to move among the options. The existing ways to navigate are: - mouse - arrow keys (typically very far from home row of keyboard) - tab (needs multiple extra tabs to get to results due to other buttons in the GUI of the krunner I propose adding Ctrl-n and Ctrl-p (for "next" and "previous" which is also what readlines, Emacs, fzf, and many more use). This would not conflict with any of the existing keybindings as far as I'm aware.
This has been rejected in the past, sorry.
