How to type

To get a radical, press the Control key and the 2 key (or the @ key) at the same time.

Press ControlKeyLeftModified2 RightModified or ControlKeyLeftModified@ RightModified

Type the radicand inside the placeholder (which is already selected).

Type x

Press the Control and 5 key (or the % key) at the same time.

Press ControlKeyLeftModified5 RightModified or ControlKeyLeftModified% RightModified

Type the index.

Type n

Get out of the radical and down to the baseline by pressing the Control key and the Space bar at the same time.

Press ControlKeyKeyBarSpaceKey

How to type

First, repeat the steps of the example for .

Press ControlKeyLeftModified@ RightModified, type x, press ControlKeyLeftModified% RightModified, type n, press ControlKeyKeyBarSpaceKey

Now type the second radical in the same way as the first.

Press ControlKeyLeftModified@ RightModified, type y, press ControlKeyLeftModified% RightModified, type n, press ControlKeyKeyBarSpaceKey

How to type

Press Control-@ to get a radical sign.

Press ControlKeyLeftModified@ RightModified

Type the expression in the placeholder (which is already selected). Press Control-% to create an index.

Type x y, press ControlKeyKeyBarLeftModified% RightModified

Type the index in the placeholder (which is already selected). Get out of the radical and down to the baseline by pressing Control-Space.

Type n, press ControlKeyKeyBarSpaceKey

Another way to type

Start by typing the expression that will be inside the square root.

Type x y

Select the expression. (You can select by dragging, by pressing Control-Dot repeatedly, or by clicking the expression repeatedly.)

Select x y

Press Control-@ to put a radical around the selection. Get out of the radical by pressing Control-Space.

Press ControlKeyLeftModified@ RightModified, press ControlKeyKeyBarSpaceKey
