Cool! Though I'm glad I don't have to debug any of those expressions.

As a slight aside: I knew about the 'bc' (bench calculator) program in
Linux/Unix, and I also knew there was a 'dc' (desk calculator) in Linux/Unix
What I didn't realise, and have only just learned, is:
* dc is the original and runs RPN
* dc predates the C programming language; it is the oldest

Hehe. I remember *screaming* in frustration while using some nerdy
sed-like text editor while working at IBM 50+ years ago. My work on editors
began with those screams.

FWIW I sometime use the underscore character in a 'down' sense. So R_ ,
perhaps.
I used to write a fair bit in (La)TeX, and that uses caret ^ for
superscript, and underscore _ for subscript, so it 'feels' write to me...

For those new to trying out the plugin, I discovered that it didn't appear
to load despite adding it to my enabled plugins. What I learned is:
1. It's in the plugin list and I needed to select the rpcalc-toggle
option under the plugins menu or...

Devel now contains one more change. I've changed the *EXIT* key (which
isn't needed in the Leo tab version of the calculator) to *TOCLIP*. It
copies the "X" register - the calculation result - to the system clipboard.

When I was using TurboPascal and doing a lot of numerical 2-D integrations
with complex numbers, I actually wrote a little library module to calculate
with complex numbers as if I was using an RPN calculator. So you could
push a complex number on the stack, pop it off, multiply or add the two
I got to play with a then- just out Hewlett Packard HP-67 RPN calculator at
the age of around 14. It blew my mind ... and may well have directly led to
me doing what I do to this day.

I'm happy to say that the RPCalc plugin is now merged into the devel
branch. Enable it in your @enabled-plugins settings node by adding a line
reading *rpcalc.py*.

RPCalc is a recent discovery for me. As originally written, it runs as a
standalone program, and requires Qt5. You don't need to use the installer
package for Windows. Just download the Linux tarball, decompress it, and
navigate to the "source" directory. The file to run is - surprise! -
I have wondered about suggesting something like this for a while, so thank
you Thomas. My 'main' editor has a simple HP calculator built into it and
it was an easy step to consider one for Leo.
I didn't know about RPNCalc (I have some Android RPN apps on my phone, as
well as a real HP-35s),
