The Autoreplace feature, is a very useful addition to "Quick Messages". It can help you save your time when typing frequently used words and expressions.
The Autoreplace feature can be configured on the corresponding options page. It contains pairs of words, for example "z105" and "Be so kind to go to study 105". When typing a message, you can type a word from the left-hand column of the Autoreplace List, press Ctrl-Space and the line will be replaced with the corresponding "expanded" version (from the right-hand column).
To change an Autoreplace entry, double-click it, edit the text and press the "Add" button.
