[Jalview-discuss] problems editing sequence

[Geoff Barton]

Just to add a couple of tips:

1. As Jim says, you can only add gaps to the left of the position, so 
shift-click drag right, or go into keyboard editing mode.  Sometimes 
people think the editing is not working because they are trying to drag 
left.

2. Dragging to the right will shift the entire sequence to the right, 
which is usually not what you want to do.  To stop this, first select 
the columns of a region that includes the part you want to edit (by 
clicking on the part of the alignment where the numbers are at the top) 
- you need to make sure you have gaps to the right of the edit point 
that are within this region.  All edits are then constrained to this region.
