I just discovered the (great) Viking application for editing and viewing GPS tracks.
I am struggling to find a way to scroll the map while I am editing?adding points to a track or a route, like in the following case:

I know I can click on the "four arrow" symbol and then move the map, but this will exit the track editing mode --- I have to select "extend track" to continue each time.
I am sure there should be a better method, but I am unable to find it.
Is there a way to scroll the map while in track editing mode?
