Re: Feedback wanted: Autogap and mainpoints

Hi all.

I agree with most of the statments, but I have a suggestion that might
change things a bit.

I am quite keen on "modification keys". That is; a keyboard key that
when pressed and hold modifies the behaviour of the mouse. In this case
I would like to see a modification key which turns of autograb. Read on
to see what it implies for the semantics below.

Autograb can be on all the time, if you don't like it while moving the
whole line, just press(and hold) the modification key to turn it of

Same thing here.

Again, it is up to the user.

This is god for changing the default behaviour. It just changes the
meaning of the modifier( turning on instead of turning off ).

This is not affected by a modifier, but I think it will be to many ways
of turning autograb on an off. It will just end up confusing.
