Mathematica Tutorial: Notebooks And Documents - Wolfram Research

32 Notebooks and DocumentsWhen you have finished, press Ctrl+Space to move back down from the superscript position.You type Ctrl+Space by holding down the Control key, then pressing the Space bar.This sequence of keystrokes enters x y .In[3]:=x Ctrl+^ yOut[3]= x y Here the whole expression y + z is in the superscript.In[4]:=Out[4]= x y+zx Ctrl+^ y + zPressing Ctrl+Space takes you down from the superscript.In[5]:= x Ctrl+^ y Ctrl+Space + zOut[5]= x y + zYou can remember the fact that Ctrl+^ gives you a superscript by thinking of Ctrl+^ as just amore immediate form of ^. When you type x^y, Mathematica will leave this one-dimensionalform unchanged until you explicitly process it. But if you type x Ctrl+^ y then Mathematica willimmediately give you a superscript.On a standard English-language keyboard, the character ^ appears as the shifted version of 6.Mathematica therefore accepts Ctrl+6 as an alternative to Ctrl+^. Note that if you are usingsomething other than a standard English-language keyboard, Mathematica will almost alwaysaccept Ctrl+6 but may not accept Ctrl+^.x Ctrl+_ y Ctrl+Spacex Ctrl+- y Ctrl+Spaceuse control keys that exist on most keyboardsuse control keys that should exist on all keyboardsWays to enter a subscript directly from the keyboard.
