Key functions

webMI.keys.addCombinationListener(modifiers, keyCode, function(e){...})

Connects a callback function to keyboard input ("modifiers" : "ALT" = 1, "CTRL" = 2, "SHIFT" = 4, meta key = 8 - the modifiers can be added, so CTRL+ALT = 3).

The parameter "keyCode" contains the key code according to the JavaScript specification.

webMI.keys.addCombinationListener(0, 13, function(e) {
    alert("ENTER key was pressed!");
});

webMI.keys.addDownListener(function(e){...}, keyCode)

Connects a callback function to a key code "keyCode" and executes the function if the key is pressed.

The parameter "keyCode" contains the key code according to the JavaScript specification.

webMI.keys.addDownListener(function(e) {
    alert("ENTER key pressed!");
}, 13);

webMI.keys.addPressListener(function(e){...})

Connects a callback function to the keyboard - if any key is pressed the callback function will be executed. With "e.which" and "e.keyCode" the pressed key can be determined.

webMI.keys.addPressListener(function(e) {
    var key = e.which || e.keyCode;
    // ...
});

webMI.keys.addUpListener(function(e){...}, keyCode)

Connects a callback function to a key code "keyCode" and executes the function if the key is released.

The parameter "keyCode" contains the key code according to the JavaScript specification.

webMI.keys.addUpListener(function(e) {
    alert("ENTER key released!");
}, 13);

webMI.keys.isDown(keyCode)

Returns true if the specified key "keyCode" is pressed at the moment.
