Seconded. Posts have been getting long enough we could use this.
seconded, tho as somebody cozy with casual browsing using a mouse exclusively, some of these could also be nice to have not just as hotkeys, but as clickable options too, like a floating/sticky menu that follows the post/browser window.
especially the jumps to different sections of a post and the ability to un-Read More a post without scrolling to the bottom of it, i've had many cases of discovering the rest of the post was waaaay longer than i'd like to scroll by, lol
On several social media sites (including both tumblr and reddit, last I checked) you can press j to scroll down to the next post and k to scroll up to the previous one in your feed. On tumblr you can also press L to like the current post! it would be nice to have these options on cohost as well
A few other things it would be good to have that aren't present on other social media:
