How do I set a Mame configuration to "None"?

[jhuie]

Ok, this should be very simple.  I know I can go manually edit the configuration file.  But when I hit TAB and would like to change something to "None", how can I do that?  Any key I press substitutes that key in rather than putting the "None" back.  Know what I mean?

Assuming you're wanting to set a certain button in a game to <none>, after using TAB, select the button you want to set to <none>, hit ENTER, then hit the ESC key.

Thank you.  I see my problem....I'm using an older version of Mame.  this works fine on the current version but on the older one that I'm using when I do that it assignes the Escape key to that button.  I guess it's time to upgrade to the latest version unless there is a workaround for that.  Thanks again.

....I've never had that problem, regardless of version.
