enter versus type

In most cases, use enter rather than type. Enter encompasses multiple ways to enter information, including speech and keyboard. Enter also assumes that the user puts a value in a field and then moves the cursor outside the field (or presses the Enter button). Enter includes both the entering of the content and the action to validate the content.


Use box instead of field or text box. However, you can use fields when referring to all fields at once. For example:

  • An Embed dialog appears. Fill in the fields.

fill in; fill out

  • When referring to entering information in individual fields, use fill in.
  • When referring to completing an entire form, use fill out.

Example: Fill out the questionnaire. Be sure to fill in the required fields.

frontend (not front-end)


Don't use a filetype extension to refer to a type of file. For example, use GIF file rather than .gif file.
