I do not get how Alt+F2 and typing the whole application name (I know:
autocompletion works) can be more convenient than typing the Windows key and
typing any part of the application name (or even of its expanded name) until
the good one is selcted (which is almost immediate if the application is
often used since they are ordered in this way).
For instance, to launch Abrowser, I only need to type Windows-a-[Enter] or
Windows-w-[Enter] ("w" like Web) or Windows-n-[Enter] (my system is in French
and "browser" starts with a "n" in this language).
