As of right now, the fastest way to add an activity or a split in a microflow is
1. Right click line
2. Hover Insert
3. Click activity or split
4. Double click the new activity/split
Seeing how often a day I have to do this, it would be nice if we could just
1. Select line
2. Shift+A(ctivity) or Shift+S(plit)
And it would automatically insert the selected item and open the dialog
