Faster way to move instances

I was wondering if there's a neat trick to move instances in Virtuoso when working with large layouts? For example, I'm currently looking at a location in a large layout where I would like to move an instance to. I go to the Navigator panel to click the desired instance but the screen jumps to that instance's location so I lost the destination location. Even then, after pressing 'm' to move the instance, the action is relative to an anchor point that I'd usually would create by clicking near the instance.

It would be great if I can sort of have the same action as placing a "new instance", when moving an instance. i.e. I switch to "special move mode", click on instance via the navigator (screen doesn't jump to instance's location), press 'm', the instance appears immediately under my cursor and then I click to place it. All of this would happen while the layout editor is fixed at current location.

Does a feature like this already exist? Or is there an efficient way of handling this particular use case?

Use:

envSetVal("layout" "autoZoomPan" 'boolean nil)

and use this code - load it and then put the function abMoveAutoRefPoint() on a bindkey. It should then behave as you describe. The envSetVal will stop the navigator zooming or panning, and the bindkey will automatically set the reference point. You need to move the cursor slightly to see the ghosted image.

Regards,

Andrew.

A function that can be used on a bindkey to behave like move,
except auto-set the reference point to the centre of the first
selected object. If nothing is selected, it behaves just like
move normally does.

Can be used with:

envSetVal("layout" "autoZoomPan" 'boolean nil)

to allow the navigator to be used to select an instance when zoomed
in, and then have the bindkey move the selected object (which might
be outside the current zoom window) and then it will ghost under the
cursor in the current zoom region.
