Another keyboard issue

Question

"Clumsy fingers" might explain it, but I'm constantly hitting a wrong combination of (various) keys.
Often, in writing email, I'll touch something I shouldn't, and the system opens another reply, and hides the one I was working on. I have to close the new one, minimize Email, and find my original.
Other times, I'll be typing along and suddenly the cursor jumps somewhere (again, my clumsy fingers I'm sure), and the recent set of letters I type will appear in the paragraph above, in the middle of a line. I have to erase, come back down, restart where I left off.
The key combo(s) I'm hitting are probably considering a "feature." But not by me. I would really like to relax my fingers and hands and wrists a bit rather than constantly having to worry about hitting wrong keys.
Q: Is there any way to turn off, or at least minimize, this "feature?"

Answer 1

I think this is exactly what is happening. But with the new "feature" that allows me swipe one, two, three or four fingers on the trackpad . . . the "ignore accidental input" is now gone.
Is there a list of such shortcuts? I sometimes pull up the visible keyboard on the desktop, but I'm not fast enough to catch my mistakes there. Seems it could be added. As a new feature.
I also downloaded Key Cue, which gives me a tantalizingly short view of shortcuts available, in different programs, each time I hold down the Command key.
But I haven't found (1) a list that will stay long enough for me to use it, and (2) an explanation of how to kill lots of keyboard shortcuts that I don't use.
