I am trying to edit the following string in a one line file using Geany 1.36 on Kubuntu 20. The cursor seems to get stuck in column one and does not respond to right arrow (though it does to up and down arrows) making it difficult to edit the remaining text on this line. Alternatively if I push end then left arrow a few times Geany stops responding to further left arrow presses. Please tell me if there is something I can do to make it possible to edit this line using Geany?
