Liz,
LEFT click twice on on the group of arrows to select an individual element.
Right click, select COPY
Find a free space and Right click, PASTE
You should now have a single arrow like this
You can now click on this element and change the text it contains.
You can also treat the text as you do with other links: highlight and select the LINK symbol. Make sure that you are linking to a PAGE (not a document or other option)
When the link is complete, slide the new arrow into place
