That is not really possible since there is not an instance variable for the
slider when the sheet is up... If the user clicks ok, a Dictionary is
allocated and filled with the keys/values pulled from the sheet. I suppose I
could allocate the dict first and programmatically bind it, but even then
the dict is not an instance variable as it is passed form the sheet to the
didEndSheet callback.

In some cases the dict will already exist and the sheet will be editing its
values... Except I don't want to alter them during the process in case the
user clicks cancel.

I need only call

[configLength sendAction:[configLength action] to:[configLength target]];

Once before the sheet opens so that the textview gets a target/action from
the slider so it sets itself.
