I'm trying to create a game with Cocoa, and I need to get user input. There doesn't seem to be an available list on all the keycodes. Am I supposed to be using keycodes? I found certain values such as NSUpArrowFunctionKey, but not for other keys. The much older question on this has answers that are all outdated, using Carbon, with broken links.
The virtual keycodes are declared in Events.h (/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/System/Library/Frameworks/Carbon.framework/Versions/A/Frameworks/HIToolbox.framework/Versions/A/Headers/Events.h)
Discussion:
These constants are the virtual keycodes defined originally in Inside Mac Volume V, pg. V-191. They identify physical keys on a keyboard. Those constants with "ANSI" in the name are labeled according to the key position on an ANSI-standard US keyboard. For example, kVK_ANSI_A indicates the virtual keycode for the key with the letter 'A' in the US keyboard layout. Other keyboard layouts may have the 'A' key label on a different physical key; in this case, pressing 'A' will generate a different virtual keycode.
