Keypress vs keyup4/1/2023 ![]() ![]() ![]() Out fourth outlet: keyboard-independent key code as described here. Toggle = & 2048 (on Windows the system uses this so it is not reported) Toggle = & 256 (system uses this so it is not reported)Ĭaps Lock key (on): Outputs 1152. Toggle = & 256 (system uses this so it is not reported) Toggle = & 128 (reports 0 on Windows if a mouse button is down, always reports 0 on Macintosh) The numerical output of the right outlet is listed along with the argument to the & object that will create a toggle: Out right outlet: The output values can be sent through the & object to create toggles set by each modifier key. Out middle outlet: The key code of the released key. Out left outlet: The ASCII value of the released key. The value can be sent through the & object to create toggles set by each modifier key. Out third outlet: The output value is a set of bits representing the state of various modifier keys when the key was released. The values reported for a given key position will be fixed regardless of the language chosen, and regardless of the modifiers (e.g., the value reported when the key to the right of the left shift key is pressed will be 6 whether an English or a German keyboard layout is chosen. This outlet is useful in situations where you want to identify the position of the key rather than the key which was released (for example, when implementing a musical keyboard using the computer keyboard). Examples of keys that dont produce a character value are modifier keys such as Alt, Shift, Ctrl, or Meta. Examples of keys that produce a character value are alphabetic, numeric, and punctuation keys. The keypress event is fired when a key that produces a character value is pressed down. The values are derived from Apple's key-code definitions (e.g., a=0, s=1, d=2, f=3). Be aware that this feature may cease to work at any time. The codes are specific to individual physical keyboards as well operating system. Out second outlet: The platform-specific key code of the released key. This outlet provides the ASCII value of the released key (i.e., it outputs the text character rather than the code for the key that was released). Out left outlet: The Unicode value of the released key, in UTF-16. For multi-key combinations (such as option-E followed by E on a Mac US keyboard), only the last key release will produce output. ![]() Output is sent each time a key is released on the computer keyboard. ![]()
