Making an Em Dash in Windows

I was looking for a program that would let me insert em/en dashes etc. on Windows like I can on Macs (ie by hitting Alt+Shift+[Hypen]), when I found out that there is a similar shortcut built in. It's longer and much harder to remember, but it's much easier than searching through every glyph in Windows' Character Map. The shortcut is [Alt+0,1,5,1]. Hold Alt, then on the num-pad on the right of the keyboard, press 0151 in sequence, then release Alt and the dash will be inserted. Presumably there are other hidden glyphs that could be inserted with similar codes. I tried 0150 and, sure enough, it was an en dash.

If you can’t use the num-pad (if you're on a computer with a small keyboard, for example) you can use the Windows Character Map (usu. located under Applications in the Start Menu). When it opens, it will have a list of every glyph in Ariel (you can change the font, but for the em dash, there’s really no point). When you mouse over each glyph, its name should pop up so you can be sure you’re using the right dash, then double click it and hit the copy button—it’ll make sense when you’re looking at it.

Another idea is to make a simple html page with a bunch of different unusual characters using html code (I think the em dash is “& mdash;” without the space) so then you could just bring up that page and copy and paste from there.
