2. you are not even giving the same information that you (eventually) posted elsewhere - i.e. you want to use special characters
And just to reiterate, yes you are correct the find dialog acts a little bit differently in 2010 - go figure. The Find Next (which gets you the Enter action you want) does not appear to be the same. In pre-2010 the Next button has the default focus; 2010 does not.
You are going to have to live with it. Use a userform and try to code the actions you want.
