When typing command and function names in 2-D Math, Maple now offers quick completions for items that are unambiguous. When such an item is available, it will appear as a yellow tooltip-style popup. Pressing the Tab or Return/Enter key will insert the suggested item.

Search and replace functionality now extends into 2-D Math expressions for simple names. For example, searching for 'x' will find the x in the first term of the 2D expression x^2-y+10.

There are two types of subscripts in Maple:

Maple 17 features improvements to how subscripts are entered in both of these cases, and well as removes the need to enter a backslash in order to explicitly create underscore characters in variable names.

Maple's long history and extensive math library have invariably claimed some names that you may want to use for something else. For example, the capital letter 'I' in Maple means the imaginary unit, but why not the identity matrix instead?  Similarly, after defining variables, A, B, and C, why can't you continue the pattern and use D? In Maple 17 you can.
