Many applications do not have standard shortcut for keybindings.
Ctrl + Shift +, => Preferences
Configure keyboard shortcuts may be Ctrl + Shift + K or simply F12.
Indeed, there is no standard shortcut for it. Adding one is pretty easy--the hard part is using a shortcut that doesn't conflict with any shortcuts used in any existing KDE apps.

Wanna give it a try?
I'll try to figure smth out =)
