How to add keybindings to a gtk3 application?

[Dat Nukka]

I'm trying to add keybindings to a gtk3 application via css. This is what I have so far:\[code\]// add style providerGtkCssProvider *css = gtk_css_provider_new(); gtk_style_context_add_provider_for_screen(gdk_screen_get_default(), GTK_STYLE_PROVIDER(css), GTK_STYLE_PROVIDER_PRIORITY_APPLICATION); gtk_css_provider_load_from_path(css, "bindings.css", NULL);\[/code\]This is the 'bindings.css' that is loaded in the previous code segment:\[code\]@binding-set tree-view-bindings { bind "j" { "move-cursor" (display-lines, 1) }; bind "k" { "move-cursor" (display-lines, -1) }; bind "slash" { "start-interactive-search" () };}GtkTreeView { color: #F00; gtk-key-bindings: tree-view-bindings;}\[/code\]The color setting works, so it can't be completley broken. But none of the keybindings work. What am I missing?
