Only for events that are linked to the component, like OnClick for a
button. These change name when the button changes name. But no other
references to the button name in code are fixed...

I tested with the following:
var
  ..
  Data: string;
begin
  ...
  Data := 'something';

Then I changed the declaration to DaTa.
If I now put the cursor at the declaration name and hit Ctrl-Space a
list is shown that starts with Date.
And if I put the cursor in the reference in the code and hit
Ctrl-Space a list is shown which starts with DaTa : string;
So if I know that an identifer needs to be fixed I can use this
shortcut to change it but it won't modify anything else so all other
instances of the wrong casing stays the same...

This actually does work by finding all references to the same
identifier within scope and renaming to whatever is put into the
editbox.
Although not entirely what I was looking for it may still help to
clean up the code after typing along without proper casing.
