Millisecond Feedback Duration Keyword

<msFeedbackDuration N>
<msfbdur N>
<msfbd N>

    Parameter and switch to set the feedback duration to N ticks or N milliseconds in the millisecond variants released in version 6.5.2.0.  Normal feedback timing is to generate the feedback display once a response has been received, schedule it to be displayed in two ticks, generate a blank display to erase it and schedule that to be displayed 32 ticks after the feedback.  The scheduling of feedback does not affect the use of <delay> so if you set a short display interval you could have feedback frames interspersed with the frames of the next item (feedback was never intended to be used in rigorous timing scenarios).  The millisecond variants were added because as time goes by more and more machines have refresh rates other than 60 Hz so in order to have a consistent experience across machines it now becomes necessary to add <msd -800> <msfbdur 533> to the parameters. lines of item files
