how can I tell what game belongs to a key?

[Orge Lambart]

Purchased a bundle from GMG, and for some reason the keys they sent me were all out of whack, I only need one of the 7 games they sent me, and it was incorrectly labeled as another game..

I know sometimes you put the key into the activation section and it tells you that you already own the game, then the install button pop's up..

but now the install button isn't popping up so I don't know which keys are which..

Is their anyway to force the install button to pop up so I can tell which key belongs to which game?

if you already know you own the other 6 games, then i would do in a webbrowser:
1. go to: https://store.steampowered.com/account/registerkey
2. put in the key in the "Product Code" field
3. open the console > go to the "networks" tab
4. click the "continue" button.
(remember to tick on "I agree to the terms of the Steam Subscriber Agreement")
5. in the neworks tab scroll down to you see "ajaxregisterkey" and click on it once.
6. go to "preview" > click on "purchase_receipt_info" > find "line_items"

example:
line_items: [{packageid: 81920, appid: 0, line_item_description: "SHOWTIME 2073"}]

just a revist to simplify this:
1. go to: https://store.steampowered.com/account/registerkey
2. open the console and paste the below (change the product_key in the parameters)

new Ajax.Request('https://store.steampowered.com/account/ajaxregisterkey/',
{
	method:'post',
	parameters: {
		'product_key' : 'ZWFQT-MALIK-QAYUM', //example steam key
		'sessionid' : g_sessionID
	},
	onSuccess: function(transport){
		g_bRegisterKeyCallRunning = false;
		if ( transport.responseText ){
			try {
				var result = transport.responseText.evalJSON(true);
				console.log(" Game: "+JSON.stringify(result.purchase_receipt_info.line_items[0].line_item_description));

			} catch ( e ) {
				// Failure
				console.log("probably invalid steam key..")
			}
		}
	}
});
