I use the macro text replacement software known as Shortkeys quite a bit for things like:
Marking code sections as “revised, when revised, by whom, & what the code looked like before”
Tagging code as “this needs revised”
Entering my email address typing just “]]e” instead of “”, etc., etc.

However, when I use it in Xojo’s editor it is extremely slooooow and frequently does not work at all. Does anyone know of a fix for this?
