Missing titletip: In the reply form of this forum, almost all icon buttons have titletips that explain what they do, but the white up-then-right arrow button does not have a titletip. It looks similar to the “reply” button down-then-left arrow, so it looks like it will immediately send the message, but differently in some unexplained way, maybe it “forwards” the post “up” to moderators.
Its html has a label attribute that did not match the icon, something about selecting a filter.
After finally opening an empty reply to try clicking it, it turned out to be a menu (with a single command to open a new topic with a link back to the replied post). That this is a menu is not evident from the button.
Please add a titletip to this button.
