Adding a Link to Another Page in Concrete5
If you're making a link to another page on your website, you should use the "Insert Link to Page" link in the blue bar at the top of the content block editing overlay window. This lets you pick the page from the sitemap easily. It also lets concrete5 rewrite the link URL on the fly, so if you move your page somewhere else or change its name, the link in your content block will automatically be updated to match.
If you're linking to a page on some other site, you'd use the Add / Edit link icon
