When you don't understand a template, move your mouse over it and you'll see a useful ``balloon help''.

The editing operations performed using a MathML palette are repeatable. That is, suffice to click elsewhere and press Ctrl+A (Cmd+A on the mac) to repeat the same replacement operation.

The editing operations performed using a MathML palette can be recorded using the macro recorder (Tools → Record Macro → Start).

The MathML tool has a "Text & Space" palette. Use it if you want to insert text which is not mi, mn or mo.

If you want to edit an mtable, for example add a column to a matrix or add an equation to a set of equations, use the table editing commands found in the DocBook menu (e.g. DocBook → Column → Insert Before) and in the MathML menu (e.g. MathML → Row → Copy).

If you want to insert special characters, use the Characters tool or use the "Insert MathML Character by Name" found in the DocBook menu and in the MathML menu.

It is fairly easy to tweak the look of an equation created using the MathML tool. For this, you'll generally insert mspace elements (Edit → Insert After), wrap one or more elements into a mphantom or mpadded element (Edit → Wrap) or specify attribute values using the Attributes tool. Of course, doing this requires you to learn MathML presentation markup.
