The right mouse button—beloved by geeks for its power, theoretically unnecessary on a Mac, and generally under-utilized on the average desktop. Right-clicking can be a powerful tool for automating file actions and saving yourself time and arm effort, but only if you've put your own stamp on the offerings of that secondary button. Today we're rounding up some of the best tools for adding power and precision to your right-click menu on Windows, Mac, and Linux systems, so check out what can be done from the other side of the scroll wheel.

10. Add convenient actions to Nautilus (Linux)

The default file manager for GNOME-based Linux systems has a pretty sparse right-click menu when first installed. Install a few helper packages, however, and soon you're rotating and resizing images without an editor, popping open terminals for quick system work, and skipping the sudo command entirely with a "Run as administrator" link. Ubuntu users can install the nautilus-gksu, nautilus-image-converter, and nautilus-open-terminal packages for starters; users of other distributions should search their package manager for "nautilus" (or "konqueror" for KDE-based systems) to see what's available for quick right-click fix-ups.

9. Use two fingers for trackpad right-clicking

If you're new to Macs, or you just haven't dug deep into its configuration options, it's easy to miss this one. Mac laptops only have one button; instead of stretching your hands an octave-length to the Control key, put two fingers on the trackpad and click. To enable it, head to the Keyboard & Mouse section of System Preferences, under the Trackpad section, check this option: "For secondary clicks, place two fingers on the trackpad then click the button."

8. Get Google Map directions without a street address

You can know where "that restaurant with the good burgers" is (a few blocks over from the big intersection) without knowing an actual street address. Find the general spot in Google Maps, right-click, and click for directions to or from that area. You might find it helpful, or you might not truly appreciate it until you're on a scarcely-there Wi-Fi connection, trying to find a way across town and furiously Google-ing for possible addresses.

7. Make one-click FTP uploads with RightLoad

Anyone with access to their own web space, or with a need to do a lot of FTP transfer, should add RightLoad to their file-swapping arsenal. Set up your FTP servers in RightLoad's preferences, and sending files to the server is as easy as right-clicking and choosing a server. After you're done, RightLoad creates HTML-formatted links for quick web writing or friend-linking, and automatically renames duplicate files. Your overworked FTP client thanks you for the downtime.

6. Tweak Windows' Send To Menu

If you're not a fan of installing contextual applications or power toys on your system, Windows' built-in "Send to" menu on the right-click box can offer a lot of flexibility—you can create instant shortcuts, email or open a file, and much more. Lifehacker reader Howard Dickens explained the process for adding "Send To" actions and items in Windows 98 and XP; for the Vista method, check with the How-To Geek.

5. Customize the Mac Finder's actions with FinderPop

One of those apps that gives back the more that's put into it, FinderPop is a hugely customizable tool for cutting down the number of clicks needed to copy, move, or alias files between locations on your Mac. FinderPop can also launch applications or kill runaway processes, making the right-click (or Ctrl-click) menu a powerful launching pad.

4. Add or delete context items with ShellExView

Programs come and go from your computer, and even after they're thoroughly scrubbed, they can leave behind annoying traces in your context menu. ShellExView is where you get complete control over what shows up when you right-click a file, your desktop, or even Internet Explorer. You can add any program, delete useless links, and otherwise hook yourself up with time-saving shortcuts.

3. Roll your own right-click Mac actions with OnMyCommand

Let's face it—some of the work you do is creative, and some of it is just resizing a bunch of images to 400 pixels wide and converting them to JPEG. Automate those mandatory tasks with OnMyCommand, an AppleScript/command-line app that adds your own scripts or already-compiled offerings to Finder's right-click menu. Check out SimpleHelp's concise and clear guide for help getting started with OnMyCommand.

2. Create file-aware right-click options

Many of the tools listed above make adding custom file-wrangling options to your right-click menu easy, but only for every file or folder you click. If you want to get specific with certain file types, adding custom for-this-file-type-only actions isn't as hard as it might seem. Adam has explained the custom context menu process (pulled from a MetaFilter thread) for Windows XP; Vista users should check out FileMenuTools, detailed elsewhere in this list.

1. Combine lots of right-click tools with FileMenuTools

If you're a Windows user and only have time to try out one of the right-click tools we've gathered here, FileMenuTools is a safe bet for maximum utility. It doesn't get as in-depth as some of the utilities it rolls together, but it lets you create contextual file actions, improve your Send To menu, add super-helpful tweaks like "Run Command Line from Here" and "Copy Path," and generally geek out your right-click menu without touching the registry or hunting down obscure command line options.

Right-click menus are definitely a to-each-their-own tool, as the most useful tools depend on what you're trying to get done. So we ask our dear readers: What right-click actions, links, and tweaks help you act quickly and shuttle files more efficiently? Share your own tips in the comments below.
