Didn’t know you can set custom edit steps, cool.
I do use uneven step edits often when trying to add variations to dense note-event filled tracks, use them to delete hits sometimes onbeat, other times offbeat. I guess stuck from the olden tracker days, the F9 to F12 keys still get used a lot travelling through patterns, cutting whatever pattern length that is being used in 4s. Page up & page down keys are also handy in that regard, same as for the home & end keys for fast travel 
. I love the flexibility.
Lill OT; once suggested a tool keyboard shortcut which will set the edit-step amount based upon the amount of pattern lines in between 2 note events where the cursor is placed.
