Parenthesis
===========

   Parenthesises can be entered manually, but when embracing large
expressions it is often easier to read if the height of the parenthesis
is the same as the height of the embraced expression. This is what this
gadget is for. Clicking on it will open a new moveable window which
contain four gadgets with different types of parenthesises or similar
symbols. Clicking on one of these enters the beginning parenthesis and
the end parenthesis with cursor between them. Entering high expression
will let the parenthesis grow as the expression grows.

   Shortcut keys is done in the  Set Key menu.

   Note: currently the parenthesis-symbols doesn't grow, so it only
makes a difference in the  LaTex output, but it is to be implemented
fully very soon.
