Thanks Chris, but WB is not one of the choices assignable to a User button. Assignable choices are REC REVIEW, SPOTLIGHT, BACKLIGHT,ATW, ATWLOCK, GAIN:24db,YGET,DRS, TEXT MEMO, SLOT SEL, SHOT MARK, MAG A LVL,PRE REC,PC MODE,WFM, FBS.
I was looking to see why I could not toggle using the process described in the first post of this thread.
