Similar to KDE's KMouseTool, GNOME's Mousetweaks provides functions for simulated secondary clicks, dwell clicks, and pointer capture. Additional information on Mousetweaks can be found at http://library.gnome.org/users/mousetweaks/
In Fedora, Mousetweaks is packaged and can be installed by selecting System > Administration > Add/Remove Software and then typing Mousetweaks; or in a terminal window, type su -c "yum install mousetweaks".
