Make file executable:
sudo chmod +x /usr/bin/toggle-keyboard.sh

create the file which the taskbar will read to load our toggle button:
sudo nano /usr/share/raspi-ui-overrides/applications/toggle-keyboard.desktop

WITHIN FILE CODE

we need to copy over the default configuration file over to our pi users config folder.

cp /etc/xdg/lxpanel/LXDE-pi/panels/panel /home/pi/.config/lxpanel/LXDE-pi/panels/panel

we need to modify the configuration for the pi user so that the icon is added to the taskbar.

nano /home/pi/.config/lxpanel/LXDE-pi/panels/panel
