Re: NSTextfields and keyboard equivalents - am I missing something?

In "The Path Of Key Events" in the URL you posted, the #1 item in the
list is "key equivalents."
AppKit checks keyDown events to see if command is held; if it is, it
tries to match it against the menus before passing it through the
responder chain.
I think your best bet is to dim your menu item or remove its key
equivalent when a text field gains first responder, and then restore it
when the text field loses first responder.
