keyboard
I have a laptop with a full keyboard (it has numpad), but the laptop is not that big, and because of that the keys are relatively small, which means I am constantly finding myself pressing keys accidentally on the numpad part.
Is there a way to disable specific keys that I simply don't want?
I am not sure if it works for all models, but on mine if you press Fn+Esc it changes the Fn lock so that F1+F12 work as normal and when you hold Fn+(lets say F11) it will change the brightness or whatever that keys secondary function is. Pressing Fn+Esc again reverts it back to default. Hope this helps.
To Disable/Enable the keyboard, just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:
xinput -list
Once you find your ID, then
sleep 0.1 ; xinput set-prop 9 'Device Enabled' 0 ; sleep 5 ; xinput set-prop 9 'Device Enabled' 1
sleep 5 is the number of seconds (I guess) you want the keyboard to be disabled.
For more information on the xinput command see the ManPage.
Or you can use Lock keyboard utility.

I have the
Menukey very close to the Ctrl and left-arrow keys.To get a first impression what keycodes are mapped to which keys, just type:
which gives you a list of all mappings. For example, the line
means that the keycode 57 is mapped to a lowercase "n" if no extra key is pressed, and an uppercase "N" if Shift is held.
Some references to get around with things.
xevwill let you identify the keycode for your key of interest.Look at its man page, This is a good quick reference too,
