Here are some keyboard shortcuts you can use for Windows, sent over by our own Ken Circeo, author of the “Under the Influence” column:

* Minimize all open windows by pressing Windows Key + M
* Display My Documents by pressing Windows Key + E
* If your PC is password protected, you can lock it by pressing Windows Key + L
* Quickly switch between open windows by pressing Alt + Tab
* Ctrl + Z, X, C, V — Undo, Cut, Copy, Paste Because these are for the most part universal among Windows programs, I tell people to try them out even if their program’s interface makes no mention of them. They usually work.
* When selecting files from a list in Explorer, Ctrl + click lets you select multiple files, Shift + click lets you select multiple contiguous files, and Ctrl + Shift + click lets you maintain the noncontiguous selection while you select multiple contiguous files.
