When you write “the emacs documentation”, you mean mg’s documentation I assume…
C-h is a prefix key for many help commands in qemacs.

Sorry, the macros were bogus, I forgot the variable name, here is a better
version:
define_kbd_macro("show-dot-files", "M-x set-variable RET dired-show-dot-files
RET 1 RET", "f2");
define_kbd_macro("hide-dot-files", "M-x set-variable RET dired-show-dot-files
RET 0 RET", "f3");

There used to be a Debian package for qemacs, but the maintainer probably gave
up…
The current version should compile fine on Debian.
