"Δ" and "γ" are entity references, and it is not clear whether
you mean the references or the characters denoted by them. Apparently the
characters, so it would be better to say just "such as delta and gamma" (or
omit these words, since anyone who does not know what Greek letters are
will probably fail to understand the question anyway).
The answer is that it depends.

This depends on what you mean by "English keyboard". A physical keyboard
can be configured in many ways, and switching between different keyboard
layouts is easy as soon as you've learned how it works. The difficult part
is to memorize the assignments or to use a cheat sheet to check them.
Naturally, this also depends on the underlying system, available fonts,
etc. And what happens to the Greek letters when the form is submitted is
yet another story.
As so often, the crucial question is "why do you ask?" Are you asking about
browser usage, or about authoring? In the latter case, what is really the
problem you are trying to solve?
