Mike you would still need to bypass all the special key code combinations which is what Staggers says the client does not accept.

The client does not want to use Alt+0188 to access a glyph that replaces the existing ¼ glyph.

The client wants to be able to use Alt+f or Alt+F to access new glyphs, but Windows and all other existing Operating Systems reconize this as special combinations to trigger special operations. Even if the OS did not do this you would get ! unless you replace that glyph for all instances of keyboard code 33.
