Your touch pad should do the trick.
They are called "Gestures". They are set to active by default. If it's not. Go to "Control panel > click "mouse" and find "touch pad". There you will find "Gestures". Activate it.
1. Put two fingers on the touch pad and try to move both fingers up or down. Learn how to scroll up and down.
2. Move those fingers side ways. This should do the "Horizontal" scroll.
There are others, like:
Put one finger stationary and rotate the other. This rotates the orientation of the object.
Try it and good luck.

Erratic Pointer Movement
Here are some easy steps to take to determine the problem with a touch pad
demonstrating erratic pointer movement:
Get the latest driver from support.dell.com - Most problems
can be corrected with a simple driver download. This should always be one of the
first steps when diagnosing any touch pad problem.
Check for hand and finger placement - The most common cause
of random pointer movement is that the touch pad senses a finger or part of the
hand near the surface of the device.
Have the customer attempt to use the touch pad normally but to pay attention
to the location of his or her hands and fingers. Are any straying too close to
the touch pad?
Adjust the Touch Sensitivity and
TouchCheck settings in the Touch Pad Settings
section of the Dell Touchpad Properties.
Try an external mouse - Does this problem happen with an
external mouse attached?
The Device Select section of the Dell Touchpad Properties
has options to enable or disable the touch pad or external mouse. Try several
combinations of these settings.
If the problems only occur when the touch pad is enabled and do not occur
any time a mouse or other external device is used, then the issue is related to
the touch pad.
Check for mechanical problems - If the problem cannot be
corrected by adjusting the settings mentioned above and only occurs with the
touch pad enabled, then this could indicate a mechanical problem.
Press down on the palm rest on first the left side of the touch pad and then
the right. See if the cursor starts moving on its own.
Run Dell 32-bit Diagnostics and try to recreate the problems there. If
either of these situations occur, then replace the palm rest.
No Pointer Movement
No pointer movement from the touch pad (or track stick, if available) usually
is the result of one of two things: The touch pad has been disabled in the
driver interface, or the touch pad cable is damaged or disconnected. Follow the
steps below to determine the problem.
Connect an external mouse - In either situation, an
external mouse should still function. If it does not, try booting into Safe Mode
and testing both devices again.
Enable the touch pad in the driver settings - Using the
external mouse (or key strokes if no mouse is available), go into the Dell
Touchpad Properties. Go to the Device Select section and enable
the touch pad. If already enabled, get the latest driver from support.dell.com.
Test the device in Dell 32-bit Diagnostics - To eliminate a
potential software problem, run the Dell 32-bit Diagnostics and test the device
Check for mechanical problems - As a last resort, press
down on the palm rest where the touch pad connector is located on the system
board. If the pointer reacts in some way, then the cable may just need to be
reseated. Otherwise, replace the palm rest.

Use the touch pad to move the pointer around the screen. Run your finger over the touch pad in the direction you want the pointer to move and then click the left touch bar (this works as the left button on a mouse).
Its a special feature of laptops' touch pad that if u slide two finger(one horizontal and one vertical) simontaneously, it will zoom in or out... Try not to touch two fingers simontaneously on touch pad.... It also occurs with me... Thanks..
maybe you need to check the touch pad's driver.
make sure the touch pad are properly installed on Device Manager. Look at Human Interface Device or Mice and Pointing Device.
If there is no name for the device, you need to try re-install the driver.
This will be one of three things; 1- a driver glitch with the touch pad. Uninstall the drivers for the touch pad from the device manager, then reboot. The machine will find the touch pad and reinstall the drivers automatically. You might also look at Compaq's support site for any updated drivers or patches for the touch pad. 2- You may have a loose connection. Remove the keyboard, check and clean the touch pad connection/connector. 3- A faulty touch pad. If the other two don't work, then disconnect the touch pad and try using the machine with an external mouse. If this works, then the touch pad has malfunctioned and needs replacing. Ty these and let me know.
