Current tooltip text
- Edit source: "You can edit this page. Please use the preview button before saving"
- Edit: "Edit this page with VisualEditor"
This isn't very helpful to new users. It doesn't meaningfully explain the difference between "edit" and "edit source", and it gives advice ("use the preview button") which is better presented to the user later, when it will be immediately useful.
There's a lot of room to work on the language, but here's one suggestion:
- Edit: "Improve this page using an easy visual interface."
- Edit source: "Improve this page by editing the source code. Mainly for experienced editors."
