disable close tab (ctrl+w)
Using shortkeys to disable ctrl+w (close tab), it is not working. I've closed out of chrome, and still does not seem to work. I've setup a test for ctrl+a (select all) to select an entire webpage and it seems to work just fine. I've not attempted any other shortcut. Also, looking at the support page, you never answer questions, which is not a good start in displaying that you're inactive.
Either way, shortcuts should be managed directly through the browser, and Google should make that available instead of using an extension. Developers need to be pressing Google.

Same issue in Firefox.
Is it because ctrl+w is registered by Windows?
