But there's a catch with using inset-end or inset-begin like this to 
move out of the inset. If the cursor is at the end of the inset already 
then "command-sequence inset-end; char-forward;" will take you to the 
end of an enclosing inset if there is one, or to the end of your 
document if there is not, which can be disconcerting if all you want to 
do is position the cursor immediately after the inset.

command-sequence line-begin; inset-end; char-right;

takes care of the case when the cursor is already at the end of the 
inset (but still produces the big jump to the end of the document if the 
inset is empty).
