NSTextField: Sending action to target on every keypress

Hi all,

I want a validation routine to run for every character someone types into an NSTextField. The validation routine determines if an Okay button gets enabled. It is not good enough for me to wait until the text field loses focus, because that would require the user to click into another field or hit the tab key before the Okay button becomes clickable.

I've been trying different versions of setContinuous: and sendActionOn: to no avail. The documentation tells me these are very mouse-event-centric, not keyboard.

Am I missing something obvious here? I'd think something like this would be common.

Thanks,

Mike
