+**gdcalc** is a financial, statistics, scientific and programmers calculator for Unix and Linux. The GUI was written with **glade**(1) and uses the Gtk toolkit - so it may well be compatible with themes and other whiz-bang features of those systems.
 **gdcalc** provides both Algebraic notation (ie. conventional, TI or Casio style) and Reverse Polish Notation (RPN or Hewlett-Packard style). If you've not heard of RPN before, you are probably familiar with algebraic calculators. Very briefly, while simpler and more natural to use, RPN calculators may need some study eg. they have an Enter key instead of the equals key and are based on the use of a stack.
 **gdcalc** is based on my venerable dcalc RPN calculator which I wrote about a million years ago to learn C and curses - about 1983, I suppose.

+The original dcalc for curses (Unix console) is at [[ http://bhepple.freeshell.org/dcalc/unix/dcalcCurses.html | dcalcCurses ]] and is also included in this package.

 Note: if you are using a locale other than English, please make sure you run **gdcalc** with the following command (thanks to Gösta):
   LC_NUMERIC=en_US gdcalc &
+Note: if you get a badly drawn border around windows in **dcalc** (curses-mode in a terminal) then try this:

 ===== Extending gdcalc =====
-**gdcalc** is fully programmable (you've got the source, ninny) and I've left loads of blank keys on the GUI for you to add in your favourites. If you add functions that you think would be interesting for the world at large, please let me have the diffs and I'll put them in. Fixes also welcome ... upgrade ideas tolerated.
+**gdcalc** is programmable (quite apart from the fact that you can get the source!) and I've left loads of blank keys on the GUI for you to add in your favourites. Just click on a blank button and add your own label and (algebraic) formula. You can reference x, y, z, t and l registers eg label="**HYP**" expr="sqrt(x^2+y^2)".
+Custom keys are indicated by the prefix "CUSTOM: " in the tooltip, visible if you hover the mouse over the button.
+To change or delete a custom key, right click on it.
