6.5. Assigning a User-Defined Key Code to the Magic Keys
Apart from the previously mentioned functions, optional keys can be applied to the magic keys following
the method below.
With this function it is possible to assign keys to the magic keys that do not exist in the BHT-700, or to
execute the equivalent of a multi-key function by pressing a magic key once.
6.5.1. Assignment Method
The steps for setting user-defined key codes for the magic keys are as follows:
(1) Save a user-defined code settings file with the filename “MKeyDef.txt” in the FLASH folder of the BHT.
(2) Choose the key you wish to set from the key definition menu in the BhtShell (for further details refer to
the “BHT-700BB/700BWB/700BWBG-CE User’s Manual” or “BHT-700QWBG-CE User’s Manual”).
Backup files can be created with a backup registry.
6.5.2. User-Defined Code Settings File (MKeyDef.txt)
(1) File name
“MKeyDef.txt” (fixed)
(2) Format
<Character string inside the combo box>,<Defined code number>,<Defined code 1>,…,<Defined
code 4>
Item Display Method Setting Content

64 characters. Extra characters will

from the BhtShell key definition menu.

LT+Y, 2, 0x12, 0x59
(*) Even if the MKeyDef.txt file is deleted, key code settings will be retained (the BhtShell will display
"None"). When a different function is designated in the BhtShell, the previous key code settings will be
replaced.
