Functions
=========

   In expressions the names of variables are often written in an
italics-font, while function is written in non-italics. To avoid
changing  Mode and typing too much, the most common functions is
included in this popupmenu.  Just click on the gadget besides the
"Functions" text, and you will get listview of the functions.
Doubleclicking will enter the function at the cursor.

   Some of the functions has limits placed above or/and below the
functionname.  If you don't need the limit, just move the cursor out of
field and the limit disappears.  Moving the cursor back into the limit
and it will reappear.  Currently there is no way to get limits to a
function which doesn't have it build in already - this might change if
there is a need.

   If you need a specific function often, you can make a shortcut key
with the  Set Key menu.
