How to detect only if back button is pressed?

Detect Mac Command key being pressed in IE (Javascript)

• I have a web page that is using Javascript to detect whether the Command key on the Mac is being pressed when the user clicks a link. This works fine on Mozilla, but it appears that IE does not implement the metaKey attribute on events (event.metaKey on Mozilla detects the Command key). Here's some sample code: <script> function ck(e) { alert(e.metaKey); if (e.metaKey) { alert("metaKey is true! You are pressing the Command key.") } else { alert("metaKey is false or undefined."); } } </script> <a href=# onclick="ck(event); return false;">press Command and click here</a> Is there a way to detect if the Command key is being pressed for IE (on the Mac)? My underlying goal is to intercept the click to do some processing, but then to go to a certain url. If the Command key is not pressed, then it just uses location.href = destination_url, which sends the page to the url. If the Command key is pressed, I want to behave the same way as Mac browsers do by default, which is to open the url in a new window; in this case I use window.open(destination_url). For various reasons, I cannot simply return "true" from the onClick in order to follow the default url of the anchor tag. (I know that would allow the browser to automatically open the url in the same or new window depending on the modifier keys being pressed.)

• Answer:

  I strongly suspect the event.ctrlKey is the one you want: <script> function ck(e) { var ctrl = null; if (window.event) ctrl = event.ctrlKey; else if (e) ctrl=(Event.META_MASK || Event.CTRL_MASK) if (ctrl) { alert("metaKey is true! You are pressing the Command key.") } else { alert("metaKey is false or undefined."); } } document.onkeypress =ck; window.onkeypress =ck; if (document.layers || (document.getElementById && !document.all)) document.captureEvents(Event.KEYPRESS); </script> Please let me know if I am correct since I do not have access to a Mac.
