Then use the arrows or click there. We're talking about Auto Enclose

This is off topic.. simply use another means to select the
expression, there are several ways.

Because that is used to /replace/ the currently selected expression
with a new expression. Selection replace is how all editors work, and
we agreed we wish to minimize surprises and violations of typing

The above may be the case for other editors, but not Squeak. With
Squeak, the worst you have is:
| "type ("
(|) "i just wanted (, Delete"
When one considers all the cases where Auto Enclose helps by keeping
one's expression nestings balanced, I think the problem of 2nd line
above becomes understandable to the user, and, if it is happening
"constantly" that they will like to learn and use the better way; of
selecting the expression and pressing Command+(..
You are an experienced developer who has his ways set by now; I'm more
interested for this feature to help new users who want to be empowered
by a system suitable for power-users and not just developers..
