In the forum just after you have sent a message and you want to edit it, hitting 'e' should be equivalent to clicking the '...' then 'edit'.
Reasoning: 'e' does the same for posts, so it is natural that it should do the same in the forums. I often hit 'e' instead of grabbing my mouse and navigating to that small '...' but it never works.
edit: pressing 'e' works for forum topics that you created, but not posts (?)
