When assigning ClarisWorks macros to function keys on the Apple Ergonomic/Adjustable keyboard, the option for function key assignment is grayed out, even when the separate number/function pad is connected. However, if you go ahead and specify a function key anyway, it will work. A future version of ClarisWorks will address the improperly disabled option.
Cursor keys on the number pad do not successfully generate VT100 cursor keys sequences with the VT102 Terminal Tool 1.0.2 and earlier. This tool needs to be revised by Apple in order to support cursor keys on the newer keyboards such as the Adjustable and the PowerBook. Apple has not announced any revision plans as of 12/1/93.
Otherwise, all keys on the number pad of the Adjustable Keyboard seem to work as expected with ClarisWorks.
