The Linux part is almost correct. But for the window managers section, I tested XFCE4 and GNOME 3 only.

The text looks pretty readable to me.

The new command to change the GNOME 3 window manager's mouse button modifier is:

dconf write /org/gnome/desktop/wm/preferences/mouse-button-modifier "'<Super>'"

But <Super> is already the default on GNOME 3, since version 3.5[1].
