Just echo the following string (which will not be displayed) as output of your command "QBW_REMEMBER_ME(<content to be remembered>)" no angle brackets; escape "close round bracket" like this "\)" to store it as ")" 
* Changed: Extended warning message in case of inconsistent Pango Markup Language output ("QBW Warning! Possible Pango Markup Language inconsistent/unterminated Tag!")   
* Changed: Extended warning message in case of inconsistent/non-UTF-8 output in TestDrive output Buffer ("QBW Warning! Expected/Shown Command Output mismatch. Possible charset different from UTF-8!")

* New: Parameter Variables substitution for using with scripts which hold X and Y coordinates where a QBW was pressed/clicked: $QBW_CLICK_X, $QBW_CLICK_Y; useful for handling different arbitrary/dynamic hotspots on widgets via launched shell scripts
