I build my desktop from the austerity theme.
See the code from austh.:

IF BarIconsOn
*Shortcut "$SC1Name$" $IconsX$ $BarY$ icons\browser1.png icons\browser2.png icons\browser3.png #0O$SCFlag$ ["$SC1LClick$"]["$SC1RClick$"]
*Shortcut "$SC2Name$" 44r $BarY$ icons\txt1.png icons\txt2.png icons\txt3.png #0O$SCFlag$ ["$SC2LClick$"]["$SC2RClick$"]
*Shortcut "$SC3Name$" 44r $BarY$ icons\fileman1.png icons\fileman2.png icons\fileman3.png #0O$SCFlag$ ["$SC3LClick$"]["$SC3RClick$"]
;*Shortcut "$SC4Name$" 44r $BarY$ icons\settings1.png icons\settings2.png icons\settings3.png #0O$SCFlag$ ["$SC4LClick$"][$SC4RClick$]
...

The problem is another. The bPopup is working. The ShortCut is not.
