I see there are 2 screws into it, however it seems you can slide it back and forth.
is this mearly to remove it (giving leway so you can pivot it off), or so you can set it?
reason im asking, is you dont go playing with things you can adjust by undoing screws without knowing what your doing *cough* tps etc.
so yeh, can i unscrew it and have a play, or is it crucial it stays in the same position?
