+The **hours and minutes hands** show the current (wall-clock) time. The **seconds hand** shows the
+stopwatch elapsed seconds. **Inset dial #1** (above-left of center) shows elapsed minutes of

+current/last/best lap. **Inset dial #3** (below center) shows seconds of current time, or elapsed
+seconds of last/best lap.
+
+Press **Start|Stop** (shortcut: **[Space]**) to begin timing. While the stopwatch is running, press
+**Lap|Reset** (shortcut: **[Enter]**) to record a lap. The stopwatch can memorize the last and the
+best lap. Press **Last**&nbsp;**Lap** (shortcut: **[Tab]**) or **Best**&nbsp;**Lap** (shortcut:
+**[Shift+Tab]**) to view the recorded time of the last or best lap. Press **Start|Stop** (shortcut:
+**[Space]**) again to stop timing. Press **Lap|Reset** (shortcut: **[Esc]**) to reset stopwatch
+counters and clear lap memory.
+
+Press the **Date** switch (shortcut: **[Ctrl+D]**) or **Time** switch (shortcut: **[Ctrl+T]**) to
+enter adjustment mode. Turn the **adjustment wheel** (shortcut: **mouse wheel** or **[Up]** /
+**[Down]**) to set the desired date or time. Press the active adjustment switch (or **[Esc]**) to
+leave adjustment mode. Note: entering adjustment mode resets the stopwatch."
