Keyboard Shortcut To Send Text Strings To Program
One simple approach is
xdotool type 'text'
The xdotool works. However if you integrate it with the keyboard shortcut .. a simple xdotool type 'text' fails.

windowid=$(xdotool getwindowfocus) sleep 0.5 && xdotool windowactivate --sync $windowid type 'text'
