Jump to recent messages lacks accessibility semantics

[daniel-montalvo]

Once you select a channel on the network and new messages appear, there is a button to go to the most recent messages.

<div class="scroll-down tooltipped tooltipped-w tooltipped-no-touch" aria-label="Jump to recent messages"><div class="scroll-down-arrow"></div></div>

Adding appropriate semantics and keyboard support is recommended. You can set this to be a button (ideally using native HTML button) so that it inherits all the browser's built-in keyboard support.

you seem to know what you are doing, can you directly send a patch rather than telling us in an issue what to do?
