the *qaghwI'.* 

On my keyboard (US), next to the [Enter] key, there is a key; on top
(shift) it has two tics, on bottom it has one tic.  I press that key for
a qaghwI'.
Does it produce an apostrophe, or a right-single-quote, or a
left-single-quote?  I don't know.

It produces what Unicode calls an apostrophe, code U+0027.

In the top left corner, near the [1], there is a key with a tic that
leans back.  It has a special use in programming.  [`]  Is that a
left-single-quote?

That is what Unicode calls a grave accent, code U+0060.
