added xdotool script for Okular with description, moved pixel-based xdotool...
I have made the following changes:
- I made the directory
usage_scenarios/okular/
- I added an xdotool script for Okular based on the Umwelt Campus script used for BE certification (sus-okular_ucb.sh)
- I added a detailed description of the script (sus-okular_ucb.odt)
- I also moved the pixel-based xdotool script from Arne to this directory
