How can I tell if an accelerator key has been pressed?

I'm using a menu, tool bar buttons and accellerator keys to access menu items.
Is there a way to tell if an accelerator button has been pressed rather than the menu directly?
Thanks

Give the accelerator a diffent ID from the menu item it covers. Then the WM_COMMAND wParam parameter will contain a different ID according to whether the Menu or the Accelerator was used. Process both commands identically.

Anthony's suggestion is probably more robust and flexible, but an alternative is to examine the contents of the high word of the wparam argument provided with the WM_COMMAND message - it should be 0 if the command has come from the menu or 1 if the command cam via an accelerator.

Anthony,
Thanks, that's a very simple way to sort the problem.
