GtkFileChooserWidget Mac shortcuts not honored
The Mac Command-Shift-G does not appear to work in any GTK3 apps I tried. The problem was found in Geany, but repeats also in Inkscape 1.0 beta
The seemingly standard gtk-keys.css (attached gtk-keys.css ) works for other GTK3 things such as text edits, but not for GtkFileChooserWidget
