[Help Request] Shortcut key that doesn't undo with second keypress?

So, when making a keyboard shortcut, using the code below, pressing the key a second time removes the newly added text.

Is there a way around this, by any chance, so that pressing the key more than once does not remove the added text, but instead keeps inserting it?

Text:

<$action-sendmessage
	$message="tm-edit-text-operation"
	$param="wrap-selection"
	prefix='    '
	suffix=''
/>

Field “condition” :

[<targetTiddler>!has[type]][<targetTiddler>type[text/vnd.tidlywiki]]

EDIT: I read through TiddlyWiki’s home site, and found the parameter “insert-text”, instead of “wrap-selection” does exactly what I was asking, so I guess this is here now to help anyone looking for exaclty what I was haha
