I'm with Richard, here. I've been using M-p and M-n for years to travel the command history.

What I do need to tell my students who use a (Canadian) French keyboard is to rebind the Meta key from Option/Alt to Command. This is because the Option key on (some?) non-English keyboards is used to access characters such as {, }, [ and ].

With Stephen for this one. Granted, I'm not the most graphics heavy user, but I've only ever had to use XQuartz to display rgl graphics.

No problem of this sort here either using C-x C-w directly or from the menu.
