Help with Synaptic, please!

The attached pic shows what else will be installed along with Gnome Tweak Tool (depends (?)). In this case, it's just a couple of items. But sometimes, the list can be longer. I want to know if there's a way to save that list as a text file.

 

Hmm.. In Synaptic>File>History (copy it) or install apt-rdepends ?

For instance the other day I installed kdenlive...

 

But if I just want a list of what all would get installed if I were to install something (without actually installing it)? The picture I put up will list them so that means the information is available. I would like to have that without having to do screenshots.

 

Oh, that wasn't clear to me. Anyway why not just use the s switch to simulate an install without actually doing it ?

sudo apt-get install -s pkg-name (simulated install)

 

That should do it. Thank you
