Any ventures why a white arrow facing forward randomly appears on the control panel when driving my 5-spd 4-cyl 1992 Jeep Wrangler?
Yup, you've got it. I now realize it is the shift indicator.
Apparently this is a feature on other vehicles in addition to
Wrangler. Thanks to Redbeard, I did some further research and found
this on rec.autos.com that confirms his explanation:

My sentiments exactly. I own a '92 Wrangler and have ignored
this indicator light from day one with no apparent reprecussions.
Jeep certainly did us a favour by minimizing the annoyance of this
light. Specifically, they made it a small outline of an arrow, less
than 1" in size, illuminated with white light. This is a vast
improvement from the annoying red bar that my '83 Mustang had
(suffice it to say that that was disconnected ASAP). Jeep also
desiged the indicator such that it will turn off as soon as your
speed plateaus, even if you did not upshift. Kudos to Jeep.
BTW, I highly recommend the Wrangler.
Is that the shift indicator? Many manual transmission vehicles have
an indicator that tells you when to shift. The up arrow may be
indicating that it's time to shift up one gear.
