Throughout this manual certain terms will be used to describe the operation and structure of BEAV.
The data that BEAV is editing is held in a buffer that is structured as a byte stream. There are many commands that affect the way that this byte stream is displayed on to the screen. Whatever display mode is chosen the data in the buffer is not effected, only the presentation.
One such choice is to display the data as bytes, words, or double words. That is; 8 bit values, 16 bit values, or 32 bit values. Whatever choice is made the value of the selected size will be displayed. These values are referred to as units in this manual. Thus the `delete-forw-unit' command deletes the unit under the cursor. If 32 bit units are being displayed then 4 bytes will be deleted.
Many commands in BEAV start by pressing the `ESCAPE' key. When this manual refers to a command that requires that the `ESCAPE' key be pressed it will be abbreviated with `Esc'. Another frequently used key stroke to start commands is `CONTROL X'. This in done by pressing the `CONTROL' key then pressing the `X' key at the same time. In this manual this will be abbreviated by `Ctl-X'. Many commands contain other control characters and these will be abbreviates similarly. Thus the `insert-unit' command will be listed as `Ctl-X I'. This will be entered be pressing the CONTROL key and while holding it hitting the `X' key, release the CONTROL key then hit the `I' key.
