- Type the word you want to be shown as a link.
- Select the word.
- Click the Link button in the tool bar of the Edit Signature field. It looks like a globe with a couple of chain links.
- Type or paste the destination URL into the resulting dialog box.
Jim's method will also work, but you won't get to control how the link reads. Instead, the system will pick up the title of the linked webpage and display that.
For Leebo's troubleshooting, I find it interesting that I have a similar, but slightly different set of buttons on my mobile signature edit page. For example, I have a link remove button the OP doesn't have (but no link button).
