I am running GNOME 3.4 (Debian 7.0) and my laptop (Gigabyte Q2532), unlike all those I've used before, doesn't change application tabs with CtrlPg Up and CtrlPg Dn. This forces me to use Alt0...9, which is not always convenient. Is there something wrong with my laptop? Is this normal? How to remedy? My layout is set to English (US).Note that I tried this with a fresh user, and still get the same issue. I'm also using GNOME 3 fallback mode.
How to make Ctrl+PgUp and Ctrl+PgDn change window tabs

GtkNotebook defaults to CtrlPageUp and CtrlPageDown for switching tabs (hardcoded in gtk/gtknotebook.c). The problem is your keys are on the numpad, so they have different keynames/keysyms, i.e.: KP_Page_Up (instead of Page_Up) and KP_Page_Down (instead of Page_Down). Remapping the keys should fix it. I have no numpad on my XPS 15 to test but something like this should work:xmodmap -e 'keysym KP_Prior = Prior' -e 'keysym KP_Next = Next'You could also patch the source code, replacing all occurrences of GDK_KEY_Page_Up/GDK_KEY_Page_Down with GDK_KEY_KP_Page_Up/GDK_KEY_KP_Page_Down in gtknotebook.cSince you're on Gnome, you can make it permanent by adding it to your start-up programs. In terminal, run gnome-session-properties, then Add:Name: WhateverCommand: xmodmap -e 'keysym KP_Prior = Prior' -e 'keysym KP_Next = Next'Comment: Whatever Alternatively, create a file ~/.Xmodmap with this content:keysym KP_Prior = Priorkeysym KP_Next = Nexttest if it works with:xmodmap ~/.XmodmapLoad it at start-up with xmodmap /home/yourusername/.Xmodmap, via gnome-session-properties, xinitrc, xprofile. E.g. (note the full path for the file):gnome-session-properties >> Add :Name: WhateverCommand: xmodmap /home/tshepang/.XmodmapComment: Whatever
