Improved keyboard support for Slash search dropdown

[tonytran]

Hello, QOL improvement request for keyboard navigation on the Slash search dropdown.

Ability for the scrollbar to also follow the keyboard navigation when hitting the bottom of the list. Haven’t tested in other dropdowns, so might be a global impact or a edge case defect.

Thanks for the hard work Piri.

+1 for this !

I think this is called lazy loading ( all spaces preloaded in batches )
