 So in other words if you need a 5:6, you'll need to write t5:6. :)
 The ratio of the beat saves.  You only need to specify it once per group.

-The following behavior is optional and probably not useful to many musicians.

-However, beginners may find inspiration by picking a scale instead of using
-sharps and flats.
+```
+# change key (this will change the key of the current scale to 3 (E))
+%k=3
 
-The current scale is currently accessible as a global variable (this will be per-track soon).
+# to set a relative key, this will go from a major scale to relative minor scale
+%k+6
 
-To set the notes to match scale, 
+# you can also go down to relative minor below
+%k-6
 
-```
-# set notes to dorian mode (won't change key)
+# scale names are supported, this changes the scale shape to dorian
 %s=dorian
 
-# rotate/relative scale (will move the key note)
-%r=dorian

-# in either case, you can also use mode numbers
