Hi Roland,
This is a bug. Key equivalents with the function key mask set and
without the command key modifier are sent for both key up and key
down.
You can work around it in a future proof way with code like this:
- (IBAction)myAction:(id)sender {
if ([[NSApp currentEvent] type] == NSKeyUp)
return;

I set a key equivalent for a NSButton like this:
unichar arrowDownKey = NSDownArrowFunctionKey;
[myButton setKeyEquivalent:[NSString
stringWithCharacters:&arrowDownKey length:1]];
When I press the down arrow key, it invokes the action associated
with pressing the button *twice* (ie, my method gets called twice in
a row). This occurs no matter which function key equiv I use (except
the Help key), not just the arrow keys.
What am I doing wrong? Is there a way to set this in IB instead?
(Cocoa, OSX 10.4.9)
