I've watched many hundreds of #usability test participants compose text.

They commonly spent ⅔ of the time backspacing, in order to rewrite or try again to get it right.

Observed in:
• Call-centre agents describing a call that just ended.
• Taxpayers asking for explanation of a tax letter.
• Job applicants writing cover letters.

So… software that suggests text as you type, and text generators that write a draft for you, may save time.

I've observed the inefficiency of deleting a whole text string back to the error versus only editing the error. When people backspace, it eats the characters and words they already typed—even the correct ones.

When using a laptop (with a physical keyboard), people are less likely to move the insertion point directly to the incorrect character by using the arrow keys or by using the pointer. It's almost always deletion.

I've watched many hundreds of #usability test participants type, and so make #typos.

Most commonly, the red wavy line (spelling error) causes people to backspace to the incorrect character, thus removing what they've typed, rather than using the arrow keys to reach the incorrect character, thus leaving the correct characters.

It's rare that people right-click a misspelled word to choose from a short list of suggested corrections.
