In KATE, how can i scroll LSP symbol info from keyboard?

I’m trying to move away from neovim, and currently checking out Kate, trying to configure it to my muscle memory. Another topic has helped me with triggering LSP symbol info from the keyboard, but now I wonder, is there a way to scroll the popup from the keyboard too? Sometimes, the doc is long enough to not fit within the relatively small popup window that appears.

It appears that the popup immediately disappears as soon as any other keyboard input happens, or the mouse happens to be inside the popup but then moves outside, or if focus is lost.

Also, while I’m here, is there a way to make that popup window appear below the symbol that I triggered it from, instead of top left of the editor view?
