Inside your new post or page, click the text or icon to add a link as you normally would. Just below that it says "Or link to existing content" which is clickable. Selecting that will open a search phrase and some recent posts. Enter a search keyword or phrase and it filters those results for you. Click one and now you have the new link you wanted without leaving the page.
