Selecting and Deleting Expressions

Selecting the Next-Higher Subexpression

Select the next-higher subexpression by pressing Ctrl+..

Press Ctrl+. repeatedly:

(∫_0^ϕ)(1/(Sqrt[1-m ((Sin[θ\[VerticalSeparator]])^2)]))\[DifferentialD]θ

(∫_0^ϕ)(1/(Sqrt[1-m((Sin[θ])^2)]))\[DifferentialD]θ

(∫_0^ϕ)(1/(Sqrt[1-m((Sin[θ])^2)]))\[DifferentialD]θ

(∫_0^ϕ)(1/(Sqrt[1-m((Sin[θ])^2)]))\[DifferentialD]θ

(∫_0^ϕ)(1/(Sqrt[1-m ((Sin[θ])^2)]))\[DifferentialD]θ

(∫_0^ϕ)(1/(Sqrt[1-m ((Sin[θ])^2)]))\[DifferentialD]θ

(∫_0^ϕ)(1/(Sqrt[1-m ((Sin[θ])^2)]))\[DifferentialD]θ

(∫_0^ϕ)(1/(Sqrt[1-m ((Sin[θ])^2)]))\[DifferentialD]θ

(∫_0^ϕ)(1/(Sqrt[1-m ((Sin[θ])^2)]))\[DifferentialD]θ

(∫_0^ϕ)(1/(Sqrt[1-m ((Sin[θ])^2)]))\[DifferentialD]θ

Deleting to Destructure an Expression

Get rid of the contents of an expression and destructure it by pressing Del (or Backspace).

Press Backspace repeatedly:

(1/(Sqrt[1+(x^2)]))\[VerticalSeparator]

(1/((Sqrt[1+(x^2)])\[VerticalSeparator]))

(1/(Sqrt[1+(x^2)\[VerticalSeparator]]))

(1/(Sqrt[1+(x^(2\[VerticalSeparator]))]))

(1/(Sqrt[1+(x^\[Placeholder])]))

(1/(Sqrt[1+x\[VerticalSeparator]]))

(1/(Sqrt[1+\[VerticalSeparator]]))

(1/(Sqrt[1\[VerticalSeparator]]))

(1/(Sqrt[\[Placeholder]]))

(1/\[Placeholder])

1\[VerticalSeparator]

\[VerticalSeparator]

Another Example

Press Backspace repeatedly:

(({{a, b, c}, {d, e, f\[VerticalSeparator]}, {g, h, i}}))

(({{a, b, c}, {d, e, \[Placeholder]}, {g, h, i}}))

(({{a, b, c}, {d, e\[VerticalSeparator], \[Placeholder]}, {g, h, i}}))

(({{a, b, c}, {d, \[Placeholder], \[Placeholder]}, {g, h, i}}))

(({{a, b, c}, {d\[VerticalSeparator], \[Placeholder], \[Placeholder]}, {g, h, i}}))

(({{a, b, c}, {\[Placeholder], \[Placeholder], \[Placeholder]}, {g, h, i}}))

(({{a, b, c\[VerticalSeparator]}, {g, h, i}}))

(({{a, b, \[Placeholder]}, {g, h, i}}))

(({{a, b\[VerticalSeparator], \[Placeholder]}, {g, h, i}}))

(({{a, \[Placeholder], \[Placeholder]}, {g, h, i}}))

(({{a\[VerticalSeparator], \[Placeholder], \[Placeholder]}, {g, h, i}}))

(({{\[Placeholder], \[Placeholder], \[Placeholder]}, {g, h, i}}))

(\[VerticalSeparator]({{g, h, i}}))

\[VerticalSeparator]({{g, h, i}}))
