It is about both the Jmol application and the JmolApplet

(Jmol.js is a JavaScript library that helps build web pages using the
JmolApplet)

Correct, this is for the units.

Double click, optionally single click 0, 1, or 2 times, Double click

After your first double-click the cursor will change and then you can
'hover' over several different atoms to get different distances.

Move outside the applet to cancel the measurement.


For a distance measurment:

double click to drop an anchor
double click on the destination

for an angle measurement:

double click to drop an anchor
single click on an intermediate point
double click on the final point

for a torsion measurement:

double click to drop anchor
single click
single click
double click
