The !Chars module contains the !Chars application which is accessed from the Apps folder on the left hand side of the iconbar.
The !Chars application is a character viewer showing all the characters available in the selected font. The System Font is shown initially, click menu over the main window to see the full font list. Clicking on a character emulates a key press which allows characters to be entered that are not directly available on the keyboard; for example accented characters or special symbols.
For use with writeable icons hover the mouse pointer over the required character and press the shift key.
