Inserting specific text with an Editor Action or Command

Hi All,

In my pre-RDi days, I wrote an SEU exit program that allowed me to perform
things like:

- Insert a comment with a horizontal line across the full source width (
as an aid to make it easier to see subprocedure / subroutine boundaries
- Insert comment metadata ( either a double slash (//) or a carefully
positioned asterisk (*) followed by a hex control character ( usually x'20'
) to make the comment highlighted.

Although I do perform most of my development using RDi these days - I still
keep with the habit of inserting horizontal line separators and inserting a
hex character at the beginning of comment text to help it stand out when
view via SEU which doesn't auto-colour comments.

I have never really found an easy way to do this in RDi, mostly I scroll
about and select and copy what I need from another place in the source ( I
usually have one, even the simplest programs I write usually start life as
a copy of another program )

I did at one point create some snippets with bits of text in I could insert
but I think they only worked on CALC lines and if you tried to insert
partway along a new line, the text would insert at the beginning of the
line, not where the cursor/carat was positioned ( which of course I
understand, the line doesn't automatically get blank filled up to the
insertion point )

I think I decided that there wasn't an existing Action or Command that I
could use for this purpose and I didn't get very far on my only attempt at
trying to write my own.

Does anyone have an easy way of doing this?

In it's simplest form I guess I'd like to be able to get a predefined
character inserted at the current carat position by pressing a shortcut key.

Does anyone have a way of doing this or something similar they could point
me at?

thanks kindly,
Craig
