Wiki needs to be updated to account for new finsm features

[Necried]

At this point the wiki is outdated by 2 years - it was written back in 2019. While this isn't a top priority as the core features remain unchanged, it would be nice to update some of the images in several sections.

Thank you, I was going to post this issue!! It would be nice to update it to reference start arrows, in particular. But for now it's probably fine.

Updated keybindings to include the new "enter edit mode" using Enter.
