The Find-As-You-Type field (FAYT) is a multi-purpose field that appears at the bottom of the file display when you type.
The FAYT has a number of modes; those with specific options are:
Times
Close timeout: Lets you specify how long the FAYT field remains displayed for once you have stopped typing. Not all modes auto-timeout; for example, in Command mode the field will remain open until you press Enter or Esc or click out of the field.
Auto search: Lets you specify how long after you stop typing a search (e.g. using Windows Search or Everything) will begin.
