Sort keys are most often not defined as linguistic terms, but as abbreviation with possibly modified orthographies. In addition then may often be limtied to a space or may start by a space. These keys shuold be visualized between alternate quotation marks (without inner spaces).
Please change:
* "Sort key changed from $1 to $2" to "Sort key changed from ‹$1› to ‹$2›"
* "Sort key set to $1" to "Sort key set to ‹$1›"
* "Sort key unset from $1" to "Sort key unset from ‹$1›"
Otherwise, the sort keys are not easily to see clearly in messages to exhibit the diffrences.
Note that these alternate ‹technical quotation marks›, suitable for English or French may still be translated or reversed, e.g. in ›German‹ or 「Chinese」(it's up to translators to choose what looks the best).
