Applying "smart" typography to imported text

[Rick]

Textmaker does a great job converting regular quotes to smart quotes and hyphens to em dashes as you type, but what if I'm importing text that doesn't have these typographic features? How can I apply smart typography to imported text. With LibreOffice you can go to Tools > Autocorrect > Apply and it will convert everything. In Word, you just search for " and replace it with " and it knows what to do. Any way to do this in Textmaker?
