You don't say what actions you want or need, but it could be worth your while investigating synclient, a terminal utility which can give you masses of configuration options for synaptics pads.
Run in terminal to see all the options and the current values/settings for your system, and then play around with the values for some of them to see if you can get what you are looking for.
To change any current value you need the command
Code:
synclient <option>=<value>
where <option> is one of the options listed in the first command I showed and <value> is a value shown in that first command. For example
Code:
synclient MaxTapTime=0
would turn of completely "tap-to-click". The zero in that configuration is milliseconds, hence that value is "Off"; higher values, up to 300 in my experience will turn it on with suitable sensitivity, but find your own values by trial and error.
