This optional subkey allows you to delete built-in Microsoft Excel commands. The syntax of the line to delete commands is:
<Keyword>=<menu_bar_num>,<menu_name>,<command_position>
The definitions of <keyword>, <menu_bar_num>, <menu_name>, and <command_position> are the same as those given in the Init Commands subkey.
Caution
Don't delete the Exit command on the File menu unless you've included another way to quit Microsoft Excel!
