[Groff] A not strictly groff question

[Miklos Somogyi]

Hello Folks,

This is not a groff question but I suspect that many of you have the expertise 
and experience
to solve this riddle.

I bought a diNovo Edge for Mac, the best keyboard I have ever had.
Except that the function keys can only be programmed with the actions that 
Logitech deemed worthwhile having.

I use vi/vim and have lots of map commands in my .exrc file, however, I never 
used the "ab" abbreviation capability.
It works in text mode and needs a white space around the short string to be 
expanded.
I've tried to program lQ for left quote and rQ fro right quote, for the use of 
"text lQ text rQ text".

For rQ the following space is ok, the proceeding one needs to be eliminated:

ab rQ <Esc>i\(rq                     (that is lower case I before the backslash)

this one does it, though I don't understand how/why.

However, I can't get rid of the following space of the left quote, though I 
tried moving the 
cursor, etc (e.g. ^[[5C is the right arrow, the ^[ is the single escape 
character, made by <ctrl>v<ctrl>[), but no cigar.
I guess that some of you have already encountered and solved this problem. If 
so, please
let me know.

Thanks,

Miklos
