Method 2: Labeling an atom by pointing

---

1. Using a bond tool or the Text tool, position the pointer over an atom.

A highlight box appears over the atom.

2. Type a HotKey, for example, "c".

The label is added to the atom highlighted. If the label is a single element, such as "C", then the appropriate number of hydrogen atoms are added to the label. Repeatedly typing the hotkey will cycle the number of hydrogens.

NOTE: The last atom highlighted is always the atom labeled, even if you are no longer pointing to it (that is, even if it is no longer highlighted). This is true even if you switch documents.
