I created this script for fun and nothing more , I release it because maybe it can be useful to someone (I don't think).
this script allows you to perform actions via qdbus ,
it's similar to searching in the app menus like on unity or kde4 appmenu-addon (but badly done) , when the script is executed, you get a list of actions that you can send to the application .
work on kde application like : kate , okular , kleopatra ,gwenview , okular , etc .
don't work on gtk and qt application , just kde qt app .
This "APP" Require : xprop , xdotool , kdialog , yad.
to use it just create a keyboard shortcut that points to the script
