I have a feeling, correct me if wrong, that the intention is that it should be standard Mac Command-Shift-G. See `/Applications/Geany.app/Contents/Resources/share/themes/Mac/gtk-3.0/gtk-keys.css`
In that file, the following section appears twice, but is not honored when Geany is executed :
``` @binding-set gtk-mac-file-chooser { bind "<meta>v" { "location-popup-on-paste" () }; unbind "<ctrl>v";
bind "<meta><shift>G" { "location-popup" () }; bind "<meta><shift>H" { "home-folder" () }; bind "<meta>Up" { "up-folder" () }; }
