I think this would be a feature request, but maybe there is another option?
Since there is no way I know of to combine typed characters in the search pane we are adding a large number of special character buttons. There is no obvious indicator that this “row” of characters can slide to show more characters. Would it be possible to have this row wrap, so that more than one row is visible? OR can there be an obvious slider bar placed there if the extra characters given are not all presented on the screen.
For example, the build I’m working on now needs to include all these and this list does not include the capitals, which may / could be included. Note in the screen shot, only the characters through ê are shown.
