hello! how i can bind fn+down_arrow and fn+up_arrow as go to current line end and line start?

FN is one of those keys that I believe is almost impossible to map, in my experience at least; I’ve never been able to.

You can enter sublime.log_input(True) in the Console to see the keys the OS is sending to Sublime Text, but it’s likely that fn+down arrow acts the same as just plain down arrow. Fn key processing is generally done at a lower level than applications have access to.

FYI on my MBP fn+down is pagedown and fn+up is pageup.

ok, thx
