reverse bone movements

Hi All - took a running character from the tb template BONES library and modified it to fit the character i was building. The character’s movement is from right to left and i need it to go left to right. Tried the ‘-1’ in the properties and the character does now face the correct direction. when i hit ‘play’, the character runs backwards. Aside from reversing all the key settings for each bone element, is there a simpler method i can use. I am using TB8 on a mac… thanks, Dan
