SecondShell is a portable utility that makes Windows Explorer a lot more user friendly

SecondShell is a tool that makes window management both less fiddly and more keyboard shortcut oriented. It doesn't actually do a whole lot (it's only 200 kilobytes!), but it adds such handy features that you'll wonder why Windows doesn't include them by default.

First, you can resize windows by holding down Alt+Right click and dragging the mouse anywhere in the window. Alt+Left click moves the window. By Odin's beard, how frickin' awesome is that?! Ctrl+Alt+Arrow key maximizes your window either horizontally or vertically, and Ctrl+Alt+Numpad 1-9 moves the window into the respective corner of your screen. There's a bunch of other keyboard shortcuts, too (but Windows 7 already has most of them built-in, I think).

Netbook and laptop users: if the resize-anywhere bit wasn't enough to get you excited, you can also remap Caps Lock to act as a Middle Mouse button! No longer will it be a struggle to open links in new tabs! It should be noted that Caps Lock remapping (and some other advanced features) will require some .INI file hacking -- the FAQ should have you covered, if you've never done that before, though.

SecondShell is one of those tiny little utilities that you simply must try; it's fast, flawless, and completely portable. It's also Windows-only, I'm afraid.
