I need to be able to type em dashes in a project I'm working on, but I can't figure out how to do it on Linux. On Windows, it's ALT+0175 and on Mac it's SHIFT+OPTION+-. I'm trying to figure out the equivalent to this on Linux.

I googled around and found that the linux code is U+2015, but I don't know how to type this. What is the "U" portion of the code?

I'm doing the project with OpenOffice. I know OO has a a replace feature that turns "--" into an em dash, but I don't want to use that. I started the project in Word and when I imported into OO, and the existing em dashes are still in the document. I can cut and paste them, but I want to know how to create them.

Hope this makes sense.

Thanks

You want to look at xmodmap, which can be configured for Unicode keycodes I believe. It will assign any keystroke to any X key (including whatever Ctrl/Meta/Shift combinations you're comfortable with).

The U+ prefix just indicates that you have a Unicode character, rather than any other multi-byte character. You can't type it in as you would under Windows.

This may help, but doesn't mention Unicode (you'll have to google for that): http://www.tldp.org/HOWTO/Intkeyb/index.html
