Many apps allow both the arrow keys and CTRL-N or CTRL-P to select the next/previous item in the list. This is nice for people who have keyboards that don't have arrow keys immediately available on their keyboard, like ergonomic keyboards where they have to switch layers.
This is a nitpicky and minor change that probably no one will use but it would contribute slightly to the QOL of Kagi (when I use it)
When search suggestions pop up, make CTRL-N act like down arrow (next) and make CTRL-P act like the up arrow (previous)
