screen capture by key-stroke (not mouse) shows fingers in WinSnap

Do other programs do the same?

I am working with a pop-up part of a web-sire, the corrections of the transcription at:
https://codexsinaiticus.org/en/manuscript.aspx

So I want the “capture” to be by key-stroke, but no pointer fingers/hand showing

Which programs do that?
Or maybe a feature in WinSnap.

I can add a picture if needed.

Using
Xenforo as my research forum 
Box.com as my main long term file holder (have experience with Drivehq, Google Docs, etc.)
Linode as my host. (So even with a lot of pictures and space it is $25 a month.)
Gentleman in Germany as my excellent, occasional support.  He set up the Xenforo on Linode, I had left vBulletin.

We expect some downloads of our work here as explained in the first post:

Borislav Borisov - Bulgarian paper - epigraphy, graphology, palaeography, codicoligy, calligraphy
https://www.purebibleforum.com/index.php?threads/borislav-borisov-bulgarian-paper-epigraphy-graphology-palaeography-codicoligy-calligraphy.3023/

The first post explains what we are doing. 
The files go a long way to showing that Codex Sinaiticus is not an ancient 4th century manuscript. 

Please feel free to read and give feedback.

When there is a download, it would be nice to capture some information about who is doing the download. 
Name, email address, any comments, etc.  (At the moment I am simply using Gmail Contacts as my main contact PIM.)
Without being too obstructive. 

Any improvements you can suggest?
Anything better than Box.com?

Downloads will likely be in the dozens, or possibly hundreds, over April and May.
And we may add other files.

Would prefer not to do any programming at this time.
Not sure if Xenforo has any plug-ins that might help, but prefer to keep it vanilla.

Thanks!
