Linux: Creating a shortcut on the lxpanel > application launch bar. (quick and easy way).

First we will add a shortcut to a normal app and then modify that shortcut to fit our needs.

Procedure:

Right click over the application launch bar and select add/remove panel items.

Add a shortcut for a normal app (lets call it  XXX). Add it a the bottom to locate it easily.

Within ~/.config/lxpanel/LXDE/panels you will find some files.

Find which one contains a reference to XXX

It looks like

Button {
            id=/usr/share/applications/vlc.desktop
        }

Copy that file to your ~/bin/ folder.

Edit it to fit your needs (mostly changing the command on the Exec= line).

Edit the path to make it go to your new file

id=/usr/share/applications/vlc.desktop   -->   id=/home/yourid/bin/vlc.desktop   (path must be absolute)

Restart lxpanel

lxpanelctl restart

Now, when you click that XXX icon it should execute whatever you put on the Exec= line

I hope it helps.

If you know a better way, please say it.
