Use "CTRL+R" keyboard combination in Service Studio when in a JS/CSS modal, used to to be a huge life saver. I uses this combination all the time and it saved me a lot of time in the end of the day.
In the past updates, you start "breaking" this incredible way to find stuff inside a JS/CSS modal. First by removing the auto-select of the first finding in the list of results. Then you add a "combo box" for "find" instead of an input and finally you remove the auto focus in the "find" combo box.
Please go back to the good and old way!
Thanks
