If you own a laptop with a synaptics touchpad, you may have an issue whereby tap-to-click is not enabled, in Fedora 13.
Resolution:
> su -c "gedit /usr/share/X11/xorg.conf.d/50-synaptics.conf"
In the first Section, add two additional lines immediately before EndSection, as such:
Section "InputClass" Identifier "touchpad catchall" Driver "synaptics" MatchIsTouchpad "on" MatchDevicePath "/dev/input/event*" Option "TapButton1" "1" Option "RBCornerButton" "3" EndSection
Save, and reboot !
