Something like this may already exist for all i know, but i haven’t found it.
I’m thinking something like a ctrl-space or something that moves down to the next line with a note on it, within the current track of course.
If the cursor is moved to the first digit in the current column as well, it could make for a fast workflow for entering effect numbers over the whole pattern.
If the current column is the effect column, the cursor position would be moved to the 3rd digit.
Just rambling. But it’d be nice.

I’m an idiot. dBlue has corrected me.
