This are probably old news to most, but sometimes the old news is the best news! I was looking for a way to quickly get to my desktop but not clear anything that was on it. I’m giving, what was Konfabulator, Yahoo! Widgets another go, with the release of v4 of the Widget Engine I figured I’d dive back in, as having notes on the desktop is quite handy. To see these my first thought was to use Win+D to show the desktop, but this also cleared the Widgets away defeating the whole object. I was pointed to Win+M to minimise all open windows, which works great. This led me to looking for more, just in case there were a few gems I’d missed. Have a look yourself, freshen up your knowledge!
