How do I get a key listener to work with a combination of keys (like Shift+M)
rather than a single key? I'm using the keyCode method currently but with the
project I'm working on that forces me to map out a lot of the keyboard and gets
kind of confusing.

A snippet of my code is this:

keyListener1.onKeyDown = function() {
if (Key.isDown(77)) {
carrier1.carrierJet.gotoAndPlay(2);
delete this.onKeyDown
}

That works if I press M. How would I code it to work only if I press SHIFT+M?

Aha. Well, the answer may come as a surprise, but only because it's so
obvious, once you see it. :)

Here, you're listening for the M key, represented internally by the
number 77. You want to listen for the Shift key *in addition* to the M key,
so you'll need to use the logical AND operator in your if() statement.
Shift is key code 16 -- you can find them all under "Keyboard Keys and Key
Code Values" in the ActionScript 2.0 Language Reference" -- so this would be
your if() statement ...

if (Key.isDown(77) && Key.isDown(16)) { ... }

Make sense?

this code
if (Key.isDown(77) && Key.isDown(16)) { ... }
works for Shift+M, and works for M+Shift as well

how about this one:

var myListener:Object = new Object();
myListener.onKeyDown = function() {
if (Key.isDown(77)) {
if (_root.key == "Shift") {
carrier1.carrierJet.gotoAndPlay(2);
delete this.onKeyDown;
}
} else {
if (Key.isDown(16)) {
_root.key = "Shift";
}
}
};
myListener.onKeyUp = function() {
_root.key = "";
};
Key.addListener(myListener);

That's right.

Checking for M, so far.

Now checking the value of a variable in the main timeline. If the value
of this variable is the string "Shift", then ...

.... a movie clip by the instance name carrierJet is told to go to frame 2
and play. This carrierJet is nested inside another movie clip with the
instance name carrier1 (or carrier1 is some other object with a property
that points to carrierJet).

If if above is not true ...

.... then *if* one of the shift keys is pressed, set that root variable to
the string "Shift".

Well ... to be honest, I'm not sure what that key variable is for. If I
understood right, Angyl wanted to test for the condition of Shift and the
key M at the same time. If so, the simplest route is to simply check for
both those keys. I'm not sure why a variable help matters, but maybe you
could explain?

just trying to test either user press the Shift key 1st...:smile;

should have some other better ways to do that..

or... if in the application, "which key pressed 1st" is not important, then
your code is just perfect...

ggshow,

Aha. Okay, that makes sense.

Ehh, you work with what you have, right? That's one of the fun
challenges of programming: if the API doesn't offer it, roll your own. :)
