It lets you set up personal alarm/reminder messages which pop up on the screen at the time you specify, or you can set up commands to be executed.</para> <para>In its default graphical mode, &kalarm; displays a list of pending alarms, showing their times and details. You can create new alarms, or you can select existing alarms for modification or deletion.</para> <para>When setting up or modifying an alarm, you may either type in the alarm message text, specify a text file to display, or specify a command to execute. You can also choose the colour of the alarm message, whether it should repeat, whether to play a sound, and whether the alarm should be cancelled if it can't be triggered at its scheduled time.</para> <para>Alarms may also be scheduled on the command line, or via &DCOP; calls from programs.</para> <para>When an alarm message is due, it is displayed on each &kde; desktop to ensure that you don't miss it. The message window shows the time for which the alarm was scheduled. It usually has a defer option to ask for the alarm to be displayed again later.
