Deleting parts of an expression MathCad Help

You can avoid having to repeatedly backspace over parts of an expression by choosing Cut from the Edit menu. This will delete whatever is between the editing lines place it on the clipboard. The following example shows how you can use the cut command to delete a significant part of an expression. Suppose you want to change the expression Rather than repeatedly backspacing, you can do the following:
• Select the numerator as shown on the right.
• Choose Cut from the Edit menu. This removes the numerator and leaves behind a placeholder.
• Type x in the placeholder.You can also delete part of an expression by using either the [Delete) key or the [Kbps] key. If you use this method however, whatever you delete will not go to the clipboard. This is useful when you intend to replace whatever you delete with whatever is currently on the clipboard.To delete part of an expression without placing it on the clipboard:
• Select the numerator as shown on the right. Note that the vertical editing line is to the right.
• Press [BkSp]. Mathcad highlights your selection to indicate what you’ve proposed to delete. Mathcad takes this extra step since once you delete, you’ll have to retype the expression to get it back.
• Press [BkSp] one more time. This removes the numerator and leaves behind a placeholder. To use the [Delete] key instead of the [BkSp] key, follow the preceding instructions but place the vertical editing line on the left side of the expression.
