    <p>I am writing a browser extension that needs to attach handlers to the keyup and keydown events on all pages. I can get it working pretty well with the following content script code. </p> <pre><code>document.addEventListener("keydown",keyDown, true); document.addEventListener("keyup", keyUp, true); </code></pre> <p>I can't get this to work in Gmail though. Specifically I can't get it to work when composing the body of an new email. It will work everywhere else I have tested. I think the problem is because Gmail is calling <code>stopPropagation</code> on all keyboard events but it is difficult to debug their minimized code. I thought that setting the 3rd parameter to <code>true</code> would cause the event to be captured during the <code>CAPTURE_PHASE</code> but this isn't working. </p> <p>How can I capture <code>keyup</code> and <code>keydown</code> events while composing a new body in Gmail with a Google Chrome content script?</p> <p>Edit:</p> <p>I've ensured that my content scripts are being injected into all iframes of the DOM by adding <code>"all_frames": true,</code> to my manifest. I have even tried using the following code: </p> <pre><code>document.addEventListener("DOMNodeInserted", function (event) { if(event.type === "DOMNodeInserted") { if(event.srcElement.nodeName === "IFRAME") { console.log(event.srcElement.nodeName + " iframe detected"); event.srcElement.addEventListener("keydown", function(kevent) { document.dispatchEvent(kevent); }, true); event.srcElement.addEventListener("keyup", function(kevent) { document.dispatchEvent(kevent); }, true); } } },true); </code></pre> <p>This still doesn't fix the issue with Gmail. </p>

    1. COGmail also tends to have a lot of iframes. Make sure you are listening for events in the correct ones.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
