With ISOLDE, you have buttons in the toolbar that do exactly this. The corresponding commands are “isolde step next”, “isolde step prev”, and “isolde step atom-spec” to set the origin of the residue stepper to a specific residue (if you don’t use it, “next” starts at the first residue of the first chain). There are aliases to make the commands shorter (you have to declare the aliases once per session). I find that entering the next command and repeatedly pressing enter is functionally equivalent to hitting spacebar in Coot.

I hope this helps,

Can we navigate the protein model like in coot?

spacebar jumps from residue i to residue i+1

shift-spacebar jumps from residue i to residue i-1

ctrl-g shows a tiny window where I can input 'a1' and the cofr goes to chain a residue 1

Can you point me in the right direction? Do I have to use aliases or is it something more complicated?

Thanks
