Glad to help, Darlene. There's probably a button or a keystroke on your
machine that disables the touchpad. My old HP had a separate button as
your old machine did. This Dell requires you to hold down
the key with the orange "Fn" logo, then press the F3 key (which has an
orange graphic of the touchpad with an "X" through it on the key).
If you can find that magic widget, it MAY be available to the GUI. The
only way to find out is to run xev, put your mouse pointer in the
window that xev opens and press the button/keystroke/whatever. If you
get events, you should be able to capture those in the keyboard
shortcut thing to do the toggle.
Here's a sample event I get with the "Fn-F3" keypress:
KeymapNotify event, serial 35, synthetic NO, window 0x0,
keys: 2 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
Yours will undoubtedly differ, but the important thing is the event
itself. If you get events, the shortcut trick should work.
