Requesters:
Requesters are prompts that appear in small windows. You must respond to a requester to continue.
A requester always contains text explaining what you must do to satisfy the request.
Menu items that generate requesters are followed by an ellipses (...).
Action Requesters:
Action requesters require you to proceed with or cancel an operation by clicking on the appropriate action gadget: OK, Continue, Retry, or Cancel.
Keyboard shortcut: To proceed (OK, Continue, or Retry), press left Amiga+V. To Cancel, press left Amiga+B.
Message Requesters:
Message requesters inform you about something that occurred in the system or a program. They require an acknowledgment by clicking on a gadget.
Text Requester:
Text requesters ask you to enter text into a text gadget. The text gadget is automatically selected and text is entered at the cursor position (the small highlighted box inside the text gadget).
File Requesters:
File requesters allow you to select or enter the name of a file that you want to open or save.
A file requester contains a scrolling list of files and drawers, plus several other gadgets for locating your file. Read through the list by dragging the scroll bar up or down or selecting the scroll arrows. If your file is in a different drawer or on another disk, the gadgets in the requester allow you to look for that file.
The gadgets are used as follows:

Volumes
Displays a list of available floppy disks, hard disk partitions, and assigned directories. List the available files and drawers on a disk by clicking on the name. Click on the drawer names to list their contents. In addition to volume, drawer, and file names, the scrolling list displays the file size in bytes, file and drawer timestamps, and volume use statistics. Use the sizing gadget to make the file requester wider for viewing this information.

Parent
Lists the current drawer's parent. Selecting Parent when the current drawer is the root of a particular volume is the same as selecting the Volumes gadget.

OK
Loads/saves the selected file. Same as pressing Return. In a Load or Open requester, the shortcut is to double-click on the file name. In a Save requester, distinguished by the reversed colours on its scrolling list, you cannot save by double-clicking. This gadget can be labelled OK, Load,0r Save.

Cancel
Cancels the requester.

Pattern
An optional text gadget labelled Pattern, when present, allows use of AmigaDOS pattern matching to control the list of files. Users familiar with AmigaDOS pattern matching can enter their own pattern statements.

The standard Amiga file requester has a Control menu with the following items:

Last Name
Moves up and down through the listed names.(The up and down arrow keys or the right Amiga key shortcuts in the menu can also move you through the list.)

Next Name
The current name appears in the File text gadget; a highlighted bar appears in the list if the current name is a file name.

Restore
Recalls the scrolling list and text gadget contents that were displayed when the requester opened.

Parent
Has the same function as the Parent gadget.

Volumes
Has the same function as the Volumes gadget.

OK
Has the same function as the OK gadget.

Cancel
Has the same function as the Cancel gadget.

Delete
Deletes files from the file requester. Select the file name or type the name into the File text gadget and choose Delete. A requester appears, requiring confirmation. Select OK to delete or Cancel to return to the file requester without deleting.

Because the file requester window is an AppWindow, you can also choose a file by dragging its icon into the window. The contents of the drawer containing the icon are listed with the file's path loaded into the Drawer and File gadgets.
Font Requesters:
Font requesters list the available fonts on the system.
Fonts are sets of characters of the same design. Using font requesters, applications allow you to choose the font style and point size. Some applications might also allow you to select font attributes (plain, bold, italicized, or underlined) and colours for the text and/or background. The display box above the OK and Cancel gadgets shows an example of text in the selected font. Use the requester's sizing gadget to widen the requester to show more characters.
When you select a font name, the display box shows that font in the currently selected font size, scaling the font as necessary. Depending on whether the font is an outline font or a bitmap font, there can be a delay in displaying the font. Some bitmap fonts sizes may appear distorted.
ScreenMode Requesters:
ScreenMode requesters work similarly to the ScreenMode Preferences editor.
