I'm closing this since it was also closed by the gedit developers. They say that these keyboard shortcuts are part of GTK, not gedit and can be customized in GTK.
https://bugzilla.gnome.org/show_bug.cgi?id=630596 You might learn how to customize these shortcuts from http://askubuntu.com/questions/223986/custom-keyboard-shortcuts-in-gedit ** Changed in: gedit (Ubuntu) Status: Triaged => Invalid -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gedit in Ubuntu. https://bugs.launchpad.net/bugs/808106 Title: Shortcut for changing tabs should be Ctrl-PgDn/PgUp Status in Light-Weight Text Editor for Gnome: Invalid Status in “gedit” package in Ubuntu: Invalid Bug description: Right now, the shortcut for changing tabs is Alt-<number>, where number is the tab id, from left to right, so 1, 2 etc. But in several other applications like Nautilus, Firefox, Chromium, gnome-terminal the shortcut is Ctrl-PgDn (=select tab on the right) and Ctrl-PgUp (=select tab on the left). This inconsitency is breaking the workflow. Candidate for 100 papercuts?
