macOS Deselect textfields with button

[abcdefg12345]

I'm working on an app with multiple textfields and some of them have to be editable but i also need a way to deselect textfields so i can type some numbers using key equivalent functions

is there a way i can have a button that when i click deselects the textfields so that key equivalent functions work

thats what i did but still can't type with key equivalent

- (IBAction)editoff:(id)sender
{
    [_Field1 setEditable: NO];
    [_Field1 setSelectable: NO];
    [_Field2 setEditable: NO];
    [_Field2 setSelectable: NO];
    [_Field3 setEditable: NO];
    [_Field3 setSelectable: NO];

}

- (IBAction)editon:(id)sender
{
    [_Field1 setEditable: YES];
    [_Field1 setSelectable: YES];
    [_Field2 setEditable: YES];
    [_Field2 setSelectable: YES];
    [_Field3 setEditable: YES];
    [_Field3 setSelectable: YES];
}

the textfields are becoming non editable but is still can't use buttons

Don't worry about it i found what i was looking for

.h

@property (assign) IBOutlet NSWindow *MainWindow;
- (IBAction)Deselectfields:(id)sender;

.m

- (IBAction)Deselectfields:(id)sender
{
    [_MainWindow endEditingFor: nil];
}
