Thank you very much that is very helpful.

I guess our Actions menu menu “backbone” isn’t including the hydrogens.
You could display backbone hydrogen atoms by their names using the command line. If you have proteins that use the standard atom names, then this should work:
disp protein & @h,ha,h1,h2,h3,ha1,ha2,ha3
…or if you only want the ones on backbone nitrogens (not on the alpha-carbons):
disp protein & @h,h1,h2,h3
For your other question, you are selecting or “picking” with the mouse on the structure, Ctrl-click selects one atom or bond and you can add to that selection with Shift-Ctrl-click, as desribed in:
Pardon the delay, I was away from work yesterday.
I hope this helps,

I can hide the side chains leaving just the backbone atoms along with the ribbon I have generated. When all the atoms are visualized including the side chains and the backbone atoms, all the hydrogen atoms in the peptide, including the ones on the backbone nitrogen are shown. However, if I hide that side chains and visualize all atoms of the backbone, all the hydrogens on the backbone atoms disappear.
