would you please help me to remove just the last comma from this string?

keydown 55, keydown 0, keyup 0, keyup 55,

it should be (with other comma's between):

Tried everything (regexp and zl filter, have read this tut:

 etc and after many hours of head braking and many, may open tabs on my browser of information I have to ask you!

Is this string a message or a symbol? One way, if is in quotes:

This is a message list that I receive as a dump from the [coll] object.

The idea is to collect many keystrokes combinations (sometimes 2, 3 or a sequens of these, so the length of the message is variating a lot) and store it as a preset (for example in [patr]) en call up from a trigger.

I was repeatedly wrong not to put the message-dump in quotes with the result that all elements were separated after the [regexp] and aka.keyboard did not "understood" the result.

I can not get dump (actually a message: keydown 55, keyup 55, keydown 55, keyup 55, to a symbol) in to quotes.

keydown 55, keyup 55, keydown 55, keyup 55,

"keydown 55, keyup 55, keydown 55, keyup 55,"

[tosymbol], [sprintf] etc breaks the line into separate words or picks just the last one. Not good...

So, how to convert this:
keydown 55, keyup 55, keydown 55, keyup 55,
to this:
"keydown 55, keyup 55, keydown 55, keyup 55,"

... after few hours of reading and testing..., but thanks to this forum I found a brute solution:

I hope that there is a more elegant way, if so, please learn me!
