This set, like the other DCX sets, does not include a 1.25x "Menu" key.
Most of my modern keyboards have bottom row Ctrl-Win-Alt-space-Alt-Fn-Menu-Ctrl which cannot be populated due to the missing "Menu" key. Most of my older keyboards have bottom row Ctrl-Win-Alt-space-Alt-Win-Menu-Ctrl which also cannot be populated. There is not even a 1.25x blank to put in place of the missing "Menu" key.
Will DCX sets ever include a "Menu" key?
