Using the SHIFT key during a screen recording

Thanks for your follow-up post Erich.  I encountered the same challenge when trying to produce a simulation that involved holding the control key to multi-select items in a list.  After reading your post, I went with the prompt to hold the control key as well.  I think a solution in the Storyline software would be to add an option to the shortcut key configuration that allows not only a Cntrl/Shift + [press key] option but a Cntrl/Shift + [Select Hotspot] option.  I'm going to submit this as an enhancement idea.
