You don't actually need the number passed to the function. Just use:
var resNo = jmolEvaluate("_atomPicked.resno")

Using standard JavaScript you can have an input box that fires a
JavaScript method when ENTER is pressed. Or have a simple <input> button
next to it with a label such as "OK". The action on that would be
something like:
jmolScript("select " + document.whatever.value)

What I like to do is use the onkeyup and the onchange methods of those
combo boxes. Something like this:
<select id="combo1" onkeyup="setTimeout('doWhatever('+value+')',100)"
onchange="doWhatever(value)">
The 100-ms timeout makes it so that pressing the down-arrow key
activates the selection AFTER the selection changes in the box.

All depends upon the memory of the user's browser. You will have to
experiment.

no idea; hope not. We don't even use 1.6 for compiling.
