Created attachment 8267 patch As mentioned in #3524 and #2406, setting prev/next tab accels to Ctrl+Shift+Tab/Ctrl+Tab has no effect due to key handling in underlying libs. This is a work-around.
An updated version of this patch is avaiable at https://github.com/adsr/xfce4-terminal/
Igor referenced this bugreport in commit 205c8ed4223655f2a46e601edc013e2d205a2a21 Enable Ctrl+(Shift)+Tab as Next/Prev Tab shortcuts https://git.xfce.org/apps/xfce4-terminal/commit?id=205c8ed4223655f2a46e601edc013e2d205a2a21
Thanks for the patch, Adam! I've implemented the feature you requested. However, I decided to make it a hidden option as the Preferences dialog is already overloaded.
Great! Thanks Igor.
The hidden option has been removed: see bug #15201.
