The sysreq is on every standard keyboard that I've ever seen. Sometimes it
has a slight variation on the name. If you look for the one key you have
never used - that will be it. Find it in the upper right corner area of the
keyboard. Note that you have to hold down alt with it.

I hope you can find the alphabetic keys yourself. Nothing special, its just
the ones with R, then E, then I etc. on them. One at a time, while
continuing to hold down alt and sysreq. Lower case works fine.

It's a bit awkward but not as hard to do as to describe.
