There is just a little bit of code to make a clickable link. It's only about fifteen keystrokes, and it's a good trick to know.
<a href=""> </a>Within the quotation marks, put the full URL starting with http:// 2020 note: Probably https these days, but whatever the full link is.
and then between the bracket and the closing command, put either the same url (if you want it to look that way) or words, or a photo
It can go right in the middle of text like this: <a href="URL GOES HERE">the URL again, or other words, or an image </a> and more text in your post...
EXAMPLES, first with the code and then with what it looks like when it works:
With a URL: <a href="https://thinkingsticks.blogspot.com">https://thinkingsticks.blogspot.com</a> blah blah continued
With a URL: https://thinkingsticks.blogspot.com blah blah continued
With words: <a href="https://thinkingsticks.blogspot.com">Topics Blog</a> blah blah continued
With words: Topics Blog blah blah continued
<a href="https://thinkingsticks.blogspot.com"><IMG SRC="https://sandradodd.com/albums/c111/SandraDodd/keith/kub/kub1.jpg"></a> blah blah continued
With an image: blah blah continued
2020 addition:
On Just Add Light and Stir, my links are the full URL within the code, and then a prettier, simpler-looking link as the clickable text, like:
