System taskbar (popup notification message) integration

I'm using Translate-shell to send translation to Debian Openbox System Notification popup message (libnotify-bin and xsel debian packages used)

#!/usr/bin/env bash
notify-send -u critical "$(xsel -o)" "$(/home/user/myDocs/sw/translate-shell/build/trans -b :uk $(xsel -o))"

Above listed bash script allows to send selected text and translation to system notification popup bar. I have used openbox rc.xml to create keybinding to this script

<keybind key="A-5">
  <action name="Execute">
    <startupnotify>
      <enabled>true</enabled>
      <name>/usr/bin/seltr</name>
    </startupnotify>
    <command>/usr/bin/seltr</command>
  </action>
</keybind>

Another idea is to send selected text and translation to the customer dictionary file for future review and integration to "Flash Cards".
