You use the align tool, but with the align-to-stage option deselected. First place the two end pieces where they go, then place the remainingones between tems in the intended order. Select them all and choose the alignment tool that equally spaces things out, being sure that the align-to-stage is not selected.
FIGURED IT OUT, I had all 5 words in one text field. I broke up into 5 separate text fields, put the left word far left and the right word far right . Then used the align tools.
To align them as you want, they need to be seperate objects, and as buttons, either movie clip or button symbols.
Then if you are using the timeline/stage to build, simply select the object and either drag or use arrow keys to align individually, if you are using actionscript then just align the instances with x and y coordinants.
instance.x = 1;
instance.y = 2;
