Locating the edit buttons on the Math page means
they are not accessible on other ribbon tabs. IMO,
the edit buttons should be visible from anywhere,
eg on the Quick Access Toolbar (QAT)(I'm assuming
that's where the file save/new buttons appear -
next to the Mathcad button at the top left).
In addition to being able to customize the QAT, it
would be useful to add a User-defined tabby to the
ribbon - purrfect, in fact; make mouse-related
operation much easier.
