Ok, give me a few days. I need to catch up on a few things and I need to think about your requirements.

Ok, I think this takes care of all your requirements. If you hold 2 keys down, say left-right, then you release the left key then the right command will be executed. If you then press the up key then the right-up command will be executed. There is 1 gotcha with this code, you can't repeat the same command one after the other. If you press and hold the up key then release it the stop will run. Now you can't press the up key again, at least until you press another key first. If you press and hold the up-left keys and then you release the left key then you can't press the left key again, until you press a different key first. This is a side effect of the code I used to trap multiple keystrokes (and filling up the keyboard buffer). Be sure to change the commands, if needed.

Seems I forgot to change the function name for the 4 onmouseup button events. Swap the 4 buttons code with this:
CODE <input type="button" name="up" title="Click to move up." value="Up" onmousedown="controlIt('d38');" onmouseup="controlIt('');"> <input type="button" name="down" title="Click to move down." value="Down" onmousedown="controlIt('d40');" onmouseup="controlIt('');"> <input type="button" name="left" title="Click to move left." value="Left" onmousedown="controlIt('d37');" onmouseup="controlIt('');"> <input type="button" name="right" title="Click to move right." value="Right" onmousedown="controlIt('d39');" onmouseup="controlIt('');"><br> |

Here is another version that includes buttons. The buttons with 2 directions (like 'Up-Down') requires both the left and right mouse buttons to be pressed and held. Be sure to press the left mouse button before the right button in order to get the 'Up-Down' movement. If you press the right mouse button before the left then you will get 'Down-Up' movement. Let's say you press the left mouse button and then the right (for 'Up-Down'). Now, if you release the right mouse button then the 'Up' command will run. When you release the left mouse button the 'Stop' command will run. Let's say you still have both buttons pressed and held. If you release the left mouse button then the 'Down' command will run. When you release the right button the 'Stop' command will run. Also, let's say you still have both left and right buttons pressed and held (for 'Up-Down'). If you release the right mouse button then the 'Up' command will run. If you press and hold the right mouse button again then the 'Up-Down' command will run again. In other words, the buttons don't have the same problem as the arrow keys (you can repeat the same key sequence).

Here is a corrected version. I forgot to change the functions for the first 4 buttons and they didn't work. Now they do.

I fixed the repeat command problem and I removed some code I was using during testing. I also made the W,S,A and D keys to act like arrow keys. W=UP, S=DOWN, A=LEFT and D=Right.

I should mention that if you want to limit the browser used to IE only then you could use Active-X to run the commands directly. No need for a web server
