If you want to move 2 sprites together in the authoring mode, just select two sprites at the same time and move - but this is obvious so you must be talking about movable sprites during runtime.
There is a type of member called Film Loop, which is basically a group of sprites. To create a film loop, select any number of channels and frames of sprites in the timeline and drag them to an empty slot in a cast window.
However, there's a problem in your case - I don't think text inputs will work once in a film loop.
You can use this thing called LDM or "linked Director movie", which is basically a Director movie within a Director movie - perhaps it's an overkill though.
Or you can write a simple behaviour like this:
[tt]--
property pOffset
on beginSprite me
pOffset = sprite(1).loc - sprite(me.spriteNum).loc
end beginSprite
on exitFrame me
sprite(me.spriteNum).loc = sprite(1).loc - pOffset
end exitFrame
--[/tt]
The sprite with this behaviour will follow the movement of sprite(1).
