Here is a table comparing IQ with Windows Explorer
 
 
   Mouse Operations : comparisons with Windows Explorer
 
ACTIONS Mouse operations Explorer vs InfoQube summary Detailed explanations
Move items Click + drag & drop Same
To move items you must click in an editable area of any selected item and drag - any selected items will move with the item you drag.
You can also move items in IQ by clicking on a number in the # column or by clicking on an item bullet and dragging. This is similar to MS Word in "Outline mode"
Select multiple items Click + drag Same
For "multiple select" using click & drag in Explorer or in IQ, just click anywhere in a non editable areas (between text-number-date fields, etc.) and drag the mouse to make a selection box.

Note that in Explorer --Windows XP-- that means that you can click anywhere except the filename column since only the file name column is editable.
         [as above] Shift + Click Same To multiple select contiguous items using shift + click in explorer or in IQ, just click anywhere in an editable area (on text/number/date), hold shift, and click elsewhere. All intervening items will be selected.
Select multiple non-contiguous items Ctrl + Click Similar
In IQ:
keeping the Control key pressed - click on the number in the # column of each item you want to select.
 
In Explorer you have to click on the file name column, keeping Control key pressed.
IQ : Show items in different contexts (create multiple parent links, etc.)

Explorer : Copy items		 Ctrl + Click + Drag & Drop Different
CTRL + click + drag & drop is used to show items in a different context. This is not the same as copying. The item(s) shown in different grids/contexts is still the same item.
 
(Full copying - to produce a replica item but with a different ID number - is managed with the item context menu or the usual keyboard shortcuts.)
Create shortcuts (hyperlinks) Alt + Click + Drag & Drop In IQ:- Not yet implemented using mouse actions IQ does do this, but (currently) only using the item context menu, not with mouse actions.
 
 
 
Some of the most frequent issues while dragging and dropping an item are:
 
 
Automatic scrolling up/down in the grid, following mouse movement
 
Common problem: IQ does not scroll when mouse cursor hovers at bottom or on the scroll bar, or at the top of the grid.
 
It actually scrolls but you need to find the right spot where it starts scrolling: just a bit over the horizontal scrollbar, just a bit below the grids columns/fields title bar.
 
 
Automatic expansion of the hierarchy where the item must be dropped
 
Common problem: If an item's hierarchy is collapsed, IQ doesn't 'open' the item when mouse cursor hovers over the collapsed item
 
The item's hierarchy will actually open, but you have to hover your mouse over the [+] or [-] or whatever is the expand/collapse symbol in your case.
 
 
 
Automatic creation of sub-item upon dragging and dropping an item over an other one
 
Common problem:  dragging-and-dropping an item over another item creates a sibling, not a sub-item.
 
In order to create a sub-item one needs to drag the item (by clicking on text and dragging) & hover above the destination item, until you see this arrow (a line also shows under the item)
 
 
 
it will automatically create a sub-item.
 
 
One can also drag & drop as a child (sub-item) of a parent item by hovering the mouse over the "expand/collapse" symbol and then continue dragging the item exactly where you want it among the sub-items. A black line will appear, indicating where the item will be dropped.
