Just type it in. If you want to molest the automatically supplied argument (#1),
just highlight it and then type a command. For instance, if you highlight #1 and
type '\bm' followed by a space, the body of the macro becomes '\bm{#1}'.
If you need to repeat the argument (for instance, you want #1+#1 for some
reason), you can insert additional copies by typing '\#1'.

Just escape the hash sign with a backslash.

This is what you want LyX to display in the math inset. The default, I think, is
to display LyX's representation of the result if you used commands that LyX
knows (it knows, for instance, that \bm means show the content in bold) and a
verbatim repeat of the macro body otherwise. Note to the documentation team:
unlike in earlier versions of the math manual, I did not see this explained in
section 22.2 of the current version!
