In general, the keystroke combination Ctrl Space gets you out of special input modes (such as inside a square root, or superscript position, or subscript position). This works whether you use the palette or use keyboard shortcuts to produce the special input form (e.g., Ctrl 2 to get into square-root mode). Another approach in your situation is this: First type the expression whose square-root you want. Second select it (with the mouse). Third click the square-root entry in the Basic Input palette. That will not only put the original expression under the square-root sign, it will also automatically return you to normal input mode, outside the square-root. The key to understanding the preceding behavior (of first typing the expression whose square-root is desired) is the little FILLED-IN square under the square-root symbol in the Basic Input palette. That filled-in symbol is SelectionPlaceholder. According to Section 1.10.12 of the Mathematica Book (printed or on-line): In general, [SelectionPlaceholder] serves as a placeholder for your current selection. When you press a button that contains [SelectionPlaceholder], the [SelectionPlaceholder] is first replaced by your current selection, and only then is the result inserted into your notebook. Contrast SelectionPlaceholder with Placeholder, which appears on the Basic Input palette as a small square that is NOT filled in. The latter represents input you ordinarily type AFTER you have clicked the palette button. Diana Mecum wrote: > Hi math folks, > > This is a really simple question.
