uControl gives you the ability to take those useless keys, that you're certain would have been better fashioned as something else, and turn them into something useful. It started out as a simple hack to remap the caps lock key to a control key, but has since evolved into a fairly sophisticated means of not only remapping modifier keys, but giving your trackpad a virtual scroll wheel, or giving lefties a sensible mouse, or giving people with disabilities the ability to type with one hand.
Release Notes: This release updates the installer for Mac OS X 10.3.3, updates the daemon to work with FileVault, and fixes a bug which caused settings to not take effect at login. The "Real Function Keys" feature is not available if run on anything later than 10.3.2, since it's now covered by Apple's "Keyboard and Mouse" control panel.
Release Notes: The dreaded bug where settings were lost after sleep/logout/reboot/etc has been fixed. The modifier key to fn key remapping has been resurrected. An inverted scrolling option for scroll wheel emulation has been added. Fast User Switching is now supported. This release has been ported to 10.3 (Panther).
Release Notes: The Twerq feature has been removed due to possible patent violation; the author encourages everyone to sign the petition against software patents. Japanese localization has been partially added.
Release Notes: This release features the ability to apply settings to a particular keyboard. There is a contributed left handed mouse feature. There are a number of bugfixes, and no reboots are required to load the extension.
