Nat asks: "Here I am, plowing along at work on an ancient machine, and thanking heavens for how much easier Open Source makes my life. In particular, I've ended up settling with KDE and its main tools due to its ability to be configured into a relatively fast and lightweight environment, despite its number of features and useful tricks. I have discovered a good few of those already, but would like to ask you guys for further illumination: what are your favorite KDE tricks?"
"I am personally very fond of multi-key shortcuts, which I base on the otherwise useless Windows key: Win-A for fast access to my most used applications, Win-W for all window management operations, and so on. I have other time-savers like: KIOs for upload, download and remote edition of files over SSH, and for access to locate queries from right within any file dialog. I have many more; but what are yours?
Conversely, what non-KDE tricks make your daily work easier and faster? What currently non-existing tricks would you like to see implemented? What are the worst time-wasters you've encountered?"
