I am a bit confused. The default normal template in Word 2007 doesn't seem to allow me to insert arrows; I can put in shapes but not arrows (bit confusing?). I deleted the normal.dotm but this didn't seem to help. Other templates (there is one designed to look like Word 2003) seem to work fine. Anybody know what is going on?

Can you click on Insert ribbon - > Symbols - > Choose Arrow?

...I have no clue what is happening.

Insert - Symbol command doesn't lead to arrows, but other symbols.

When clicking insert > symbols, choose more symbols from the bottom of the window. Choose font Wingdings. Scroll down until you find an arrow you like. Other fonts such as Symbols have different arrow choices, but I like Wingdings best.
