Basically, an extra edit step option that sends the cursor to the next line with note data on it. Similar to CTRL+SHIFT+PAGE DOWN, but without having to press the keys.
I’ve found myself wanting this mainly when using sample offset - after all my notes are entered for a drum loop that I want to rearrange, it would then be helpful just to have FNN activated and then press 9 in the effects columns to enter 0900 values for each note, rather than having to engage the above key combo.
Hope that makes sense
