A lot of the default applications only use alt+f4 for close

[AJenbo]

Many of the default applications in Ubuntu will not close on the default Gnome shortcut ctrl+q or ctrl+w, instead they use a Windows style alt+f4.
This is inconsistent and really annoying when trying to establish a work-flow.

Confirmed as a papercut.

I could reproduce it on Chromium 14.0.835.202 (Developer Build 103287 Linux) Ubuntu 10.04.

For Checkbox this stems from the fact that it has no menus and thus no accelerators have been provided; only the standard "close window" function, mapped to alt+f4 by default, is in place.
We'll look at implementing this. Set as importance: medium as it's a usability issue with no impact on functionality (other than annoyance).
