I have a macOS app that has a lot of form type inputs throughout. As such I have subclassed NSPopUpButton and implemented canBecomeKeyView to return YES. This works great as users can tab through fields and pop up menus to enter data. The issue is that when tabbing to a pop up I expect the user to see instant changes as they type, instead it takes 1-2 seconds before the menu changes. If the user hits the down arrow key it expands the menu and then type selection is instantaneous.
Is there any way to make NSPopUpButton respond instantly to typing, like a select menu in a web form? As it is it inhibits fast data input as you wait for it to recognize your input before tabbing to the next field.
