feature questions about dbvis pro version 9

Hi I'm evaluating Dbvis Pro. I'd like to know it's possible on Dbvis Pro. First. is it possible to load result Set on demand? for example I set max result set count as -1 And if query results are 420,000 records , I have to wait for all the results to be fetched. So at first time shows specific amount of record like 10,000 records, and if i pushed button or vertical scroll bar is reached the end of gird, another 10,000 records are fetched from db and are appended on result grid. Second, I usally used SQL developer for oracle, It has a feature to open popup form about table or view description from editor If i hit Shift-F4 on table or view name in a query editor. I'd like to know the same feature is provided on Dbvis by shortcut key. Third , I'd like to change default mouse click event behavior on result Grid. If i double clicked on result cells or header column, On Cell Value It opens read only cell form and On Header it sorts the results , I'd like to change this behavior. i'd like cell value or header name to be copied on editor when i double click header or cell value , Is it possible to change the default behavior ? Sorry for my bad English Thanks Park
