Excuse my ignorance but I am trying to assign one of my rocker switches to trim adjust but cannot find the word TRIM in assignments. Is this known as a different name?

Keith, I believe it's under whatever specific surface you are trying to set trim for. So if you want to set it for the elevator, look for "Elevator trim", instead of just "trim".

You set it directly through FS9 or FSX control assignment interface, there is no such entry in the PMDG keyboard configuration system AFAIR as it uses the default trim facility in the sim itself.

Thanks Andy and Roth, appreciated. Andy I was actually looking up trim under the FSX assignments list. So, I assume that I am looking for ELEVATOR TRIM in order to adjust the trim on the 747? Thanks for confirmation.

Roger that Keith.
