1.10.6 Subscripts, Bars and Other Modifiers

Here is a typical palette of modifiers.

Mathematica allows you to use any expression as a subscript.

In[1]:=

Out[1]=

Unless you specifically tell it otherwise, Mathematica will interpret a superscript as a power.

In[2]:=

Out[2]=

Special input forms based on control characters. The second forms given should work on any keyboard.

This enters a subscript using control keys.

In[3]:= Expand[(1 + xControlKeyLeftModified_RightModified1+nControlKeyLeftModifiedRightModified)^4]

Out[3]=

Just as ControlKeyLeftModified^RightModified and ControlKeyLeftModified_RightModified go to superscript and subscript positions, so also ControlKeyLeftModified&RightModified and ControlKeyLeftModified=RightModified can be used to go to positions directly above and below. With the layout of a standard English-language keyboard ControlKeyLeftModified&RightModified is directly to the right of ControlKeyLeftModified^RightModified while ControlKeyLeftModified=RightModified is directly to the right of ControlKeyLeftModified_RightModified.

Ways to enter some common modifiers using control keys.

Here is .

In[4]:= x ControlKeyLeftModified&RightModified_ ControlKeyLeftModified RightModified

Out[4]=

You can use as a variable.

In[5]:= Solve[a^2 == %, a]

Out[5]=

Ways to enter modifiers without control keys. All these forms can be used only inside \!\( ... \).
