I don't think the lockscreen it's the same scenario as bash or vim, in general UI apps react to Ctrl+W by closing themselves, while gtk/qt text entries by default do nothing on ^U/^W, thus I don't think it's the case to add support for this.
If you need to quickly delete the content of the input field, you can instead use Ctrl+Backspace (or slower Ctrl+A + anything you want) which is more more standard in text entries than the shortcuts you suggested. ** Changed in: unity Status: New => Opinion ** Changed in: unity (Ubuntu) Status: New => Opinion -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu. Matching subscriptions: dx-packages https://bugs.launchpad.net/bugs/1324064 Title: lock screen doesn't allow ^U or ^W Status in Unity: Opinion Status in “unity” package in Ubuntu: Opinion Bug description: The new lock screen password input doesn't respect the ^U and ^W keyboard shortcuts. To reproduce, lock the screen and type some characters. Hit Control+U and notice nothing changes. Hit Control+W and notice nothing changes. Expected behavior: I would expect both keys to delete the entire input. (While ^W deletes words in most programs, this should probably not expose word boundaries to casual viewers.) See how bash and vim handle ^W and ^U. I'd expect the same from the password prompt.
