I often work in Greek and need to use chevrons instead of curly/straight quotes. I have tried through changing the Language preferences to no avail. I know that I can use Alt 0171 and alt 0187 for inserting opening/closing quotes but this is hardly practical, especially when the text is full of sentences that need to appear in quotes. Is there any way to assign the Alt values to specific keys of the keyboard? Any ideas will be truly appreciated.
