To post 350, if you're using NVDA, you must get the add-on that Elten has for NVDA for Braille support. Then you must enable Braille support. I believe that's in interface settings, but it's been too long since I experimented with it. All works as advertised if you have the above-mentioned add-on.

how do i go all the way to the end, without going from 2017 all the way down?

Afik, after opening the thread, press control plus period.

The moderator responded to the question without any warnings and without moving it to another thread, so I assume she tolerates it. So let me add that Ctrl+D lets you quote and reply to a certain post; Ctrl+E lets you edit a post of your own; and then there is one more shortcut that I am not sure of but if I remember right, Ctrl+N should take you directly to the field to make a new post.
Note that these shortcuts do not work in mixed threads where you can post both text and audio. I don't think I have tried that but Ctrl+D to quote another post should not work in audio-only threads either.

The only shortcut that doesn't work in mixed forums is ctrl + d. You can edit text posts, but not voice posts, and ctrl + n works without any exceptions.

Yeah, thanks for the correction.
