The key Super_L is bound to the "windows key" which I would like to use in combination with other keys to start programs. Like "Super_L+t" to start the terminal emulation.

This is impossible because the shortcut manager pays attention only to the Super_L key and not to the whole combination.

The same behaviour can be observed even if one edits the file .config/xfce4/shortcuts/mytheme.xml and changes the entry to something like <shortcut command="/home/velko/xterm/unicode_xterm" keys="Super_L+t"/>.

Reproducible: Always

Steps to Reproduce:
1. Start "Keyboard preferences"
2. Go to "Shortcuts" tab
3. Add new shortcut theme
4. Insert a new shortcut
5. When the "Set shortcut" dialog appears press Super_L and some other key
6. Press just the Super_L key - the newly created shortcut will be activated
7. (optional) Edit manually .config/xfce4/shortcuts/mytheme.xml and change the shortcut "keys" attribute from "Super_L" to "Super_L+t". This does not work either.
Actual Results:  
Pressing the Super_L key only triggers the action.

Expected Results:  
Pressing a combination of Super_L and some other key should trigger the action.
