To get a start position nobody needs a command. The OP can't always see
the cursor. It would be possible to open a text box at the current
cursor position, that follows the cursor, using xdotool and wmctrl [1],
but I would try to find a very large cursor theme and write a script to
switch between a normal cursor theme and a very large theme for using
the laptop outdoors under the sun.

There likely is a way to stop a similar script by a click. I've got no
time to search how to do it.

[weremouse at moonstudio tmp]$ cat demo 
#!/bin/bash
xfce4-terminal --geometry=30x1 -T Here\ I\ am 2>/dev/null &
i=1
#echo -e "\e[?1000h"

while [ $i -gt 0 ]; do
  eval $(xdotool getmouselocation --shell)
  wmctrl -x -R "$(wmctrl -lx | grep Here\ I\ am | cut -d" " -f4)"
  sleep 0.2 # on my machine a value of 0.2 is needed
  wmctrl -i -r $(wmctrl -lx | grep Here\ I\ am | cut -d" " -f1) -e "0,$X,$Y,30,1"
  #read -n 6
  #if [ $? != 0 ]; then
  #   echo "test" # wmctrl -x -c "$(wmctrl -lx | grep Here\ I\ am | cut -d" " -f4)"
  #fi
###push Ctrl+Alt+Fn to "killall demo" or comment out "sleep 2" to have enough time for pressing Ctrl+C
###sleep 2
