Is there a keyboard shortcut to transpose? Or do I have to through the Write menu everytime…?
I added “tp” as a Jump Bar alias.
You can also assign your own shortcut on the Key Commands page of Preferences, and furthermore you can do transposition directly from the shift-I popover, e.g. if you do shift-I and type in, say, “t m3” it will transpose by a minor third. See Transposing existing notes with the note tools popover
Thanks. Is there an additional letter specifying direction?

You can use e.g. “t -m3” or “t m3 down”.
The full reference page for what to enter into the popover for different results is here.
