⌘+L shortcut not working in Chrome Quite frequently I experience cases, where the ⌘+L shortcut will not work in Chrome.

This shortcut does the same in Safari, Chrome and Firefox. It jumps to the URL bar of the browser.

How can I troubleshoot this problem?
Several postings on the Chromium issue tracker, such as this one and this one, suggest that this is because some plugins (such as Flash) are consuming the keystrokes whilst running. Does this happen whilst Flash is running, or can you pinpoint an occasion when it always happens if a certain plugin is loaded?
