To set the alert

When you launch a new sticky, in its bottom are automatically inserted the current date and time, that are displayed in the format selected in the program menu, item 'Format of dates'.

To set an alert in the current active sticky just set date and time later than the current one: when the set date will be reached or exceeded the sticky will automatically appear in the center of screen, eventually producing an additional sound.

In order to set the alert, date and time can be changed in two ways:

In the sticky that reached the status of alert date and time are highlighted in dark red:

If you want to edit the text of a sticky jumped on top because has been reached an alert just click inside its text box (see sticky elements).
