# 3. Customisation

## 3.1. Properties

While the program is running you can use the right mouse button on the sand glass to open a popup menu. This allows you to quit the program prematurely or to change the alarm time or the alarm message. The menu's Properties entry pops up the property dialog for the timer.

The property dialog has four tabs. Most of these should be self explanatory. For example the action tab contains a sheet, where you can choose the alarm action. The options include ringing the terminal bell, playing a sound file or executing an arbitrary program.

The final entry, titled External SandUhr::AlarmAction CORBA object, can be used to plug custom alarm actions into SandUhr with the help of SandUhr's CORBA interface. This is explained in detail in Section 4.

## 3.2. Preferences

The Global Preferences item of the timer's popup window opens the preferences dialog. Here you can customise some default values, which are used for new timers. The fields are similar to these of the properties dialog.
