Something that continues to really bug me about using Windows is the interface is just so inconsistent. And I'm not talking about Microsoft-delivered apps look and act differently from third-party apps - I mean different Microsoft apps just don't behave the same.
Case in point: Ctrl-Backspace. Why doesn't it do the same thing everywhere?
Under Linux, Ctrl-Backspace always did the same thing, no matter what application I was using: it deleted the current word. For example: I always have a long passphrase, usually 10-12 characters long. When typing my passphrase under Linux, if I got 8 or 9 characters in, then felt I'd mis-typed a key, I'd just hit Ctrl-Backspace and start over.
Under Windows, this doesn't work! At login (or when unlocking the screen) Ctrl-Backspace inserts a Ctrl-Backspace character. How confusing!
Yet in other Microsoft apps, Ctrl-Backspace works "properly", and deletes the current word. It does that in MS Word, MS Powerpoint (but not MS Excel), and Internet Explorer. Use Notepad, and it inserts a Ctrl-Backspace character - but Wordpad works "properly".
I even found another instance where Ctrl-Backspace just backs up over the last character (just the same as hitting Backspace) and another instance where Ctrl-Backspace does nothing (I'm looking at you, Excel.)
These are all Microsoft apps, but they don't act the same. Why the inconsistent behavior!?
