[Chimera-users] Selected residues already shown on the screen

Dear Ibrahim,
If I understand correctly, you want to get back the selection you had  
before, which is the same as the atoms that are displayed.

If that selection was the most recent, "Select... Undo" would restore  
it.  The same thing is accomplished by pressing the left arrow key  
after clicking into the graphics window.

If that doesn't work (if you did some other selections in between),  
you can re-select just the displayed atoms with the command:

select @/display

Then you can proceed with hbond and one of its "selRestrict" options.

For future reference, you can name and save a selection ("Select...  
Name Selection" in the menu or the command "namesel") and then later  
restore that selection by choosing its name from the menu under  
"Select... Named Selections".

I hope this helps,
