They can be triggered.

The case I want to fix, with this patch: https://iskrembilen.com/screenshots/dolphinaccel.png

The "Sort by" is not possible to explicitly assign a shortcut, but it gets an accelerator which can be triggered with this patch. Without this patch the accelerator for "Sort by" gets constantly added and removed and is not possible to trigger.

FWIW, the accelerator for "Control" does not get stripped by KToolBar, so the current state is a bit inconsistent.
