Header and Footer "dropdown" list

Hi all
Is there a way to get the "dropdown" list (the bit with the $ signs on it) for the Header and Footers to stay on for longer (or until dismissed)? It closes itself before I've found what I'm looking for. As Musescore is (seemingly) infinitely configurable I am guessing that there is. If it is in the handbook, apologies, I must have given it a 'man-look'.
