TeamPlayer Enables Multiple Input Devices
Posted by Lifehacker US Edition at 9:00 AM on November 10, 2008

Windows only: TeamPlayer allows you to use multiple mice and keyboards on a Windows based system. Under normal circumstances you can plug multiple USB mice in, but moving the two simultaneously will result in Windows struggling to decide which input to use for the single cursor on the screen. TeamPlayer is designed for a group environment where multiple people will be interacting with the same computer. Each mouse is assigned a unique coloured cursor to identify it. When testing on my system my primary PS/2 mouse was assigned red, and the secondary USB mouse was assigned blue. There are two small caveats with Teamplayer:

Mac OS X only: Free application FunctionFlip adds a new preference pane to your Mac's System Preferences that lets you choose which function keys you want to operate purely as standard function keys versus special keys on a per-case basis. Say for example that you like the volume keys instead of the corresponding function keys, but you don't want to dedicate function keys to your controlling iTunes (or some version of this scenario). Normally you can only choose all function keys or all special keys by default. With FunctionFlip, you say which keys operate as special keys and which operate as the default function key (e.g., F1, F2, etc.). FunctionFlip is a simple but smart piece of freeware, Mac OS X only. 

Being on top of your grammar is a skill that takes years of practice to refine into unthinking craft, but even the most word-minded among us can trip up when it comes how keyboards transpose our thoughts. Blogger Christopher Phin releases his inner copy editor and points out 10 errors one sees everywhere in digital writing, mostly due to not knowing what characters go exactly where. As someone who over-uses the "m-dash" a bit, I was glad to get schooling in the finer points of horizontal lines:

Mac only: The new MacBook Pro models released Tuesday brought new processor power, more hard drive space, and a little-heralded but kinda nifty feature: The addition of a right Alt key (and dropping of the mini Enter key), giving keyboard enthusiasts access to "third-level" characters and a wider array of shortcuts. For those with MacBook models older than 48 hours, free remapping utility KeyRemap4MacBook can help you reassign that tiny Enter or other under-utilised keys for similar shortcut happiness. Definitely worth the effort for programmers and coders, but potentially helpful for anyone who wants to assign Mac environment shortcuts (like Spaces, for example) to non-default keys. KeyRemap4MacBook is a free download for Mac OS X 10.4 and 10.5 only.
