This is so frustrating. It;s impossible in sansar in edit mode to go up or down. It's missing on the keyboard (pgUP & pgDOWN) and it's also not available on the xbox controller.
Sansar seems not to understand how difficult navigating is without up and down. It's already hard because some key's are wrong assigned.
Request: Add up and down to xbox controller and also assign it to pgUP and pgDOWN on keyboard in edit mode.
