Minitool for viewing key assignments on the HP49+
Some people tend to forget their own key
assignments. Although Keyman supplies a key recaller it may be useful to
have a fast look at the assignment using the screen optimally.
ViewKey realizes this. It may be added in the CST menu, but better,
assign its program to a
convenient and dispensable key,
key X say.
Assume it is assigned to X (this letter may always be printed in ALPHA mode).
After having hit X simply press the key with the possibly forgotten assignment.
Then its key number is displayed in the header and the assignment
itself below it, ready for beeing scrolled if the screen is too
small. This works for shiftholds as well. The screen-shot shows a useful assignment on the TOOL key 23.1
proposed in the Appendix to Keyman.htm.
It sets the STACK menu directly if TOOL is
slightly longer hold. (STACK denotes a submenu of TOOL, permanently used by
programmers). Mode sensitive assignments made with Keyman are SysRPL programs
and other professional key assignments may even be code objects. ViewKey
chooses a suitable
decompiler automatically. Decompilation depends on certain flags you need not care about.
Still a pleasant surprise: All the above works also while progamming, to
expand the information range without leaving the editor. After viewing a key
assignment you nicely return to
the edit line. Clearly, for decompilation library
extable should be in port2. Those who
don't understand SysRPL are not
lost. The assignment is readable as well if its components are written in UsrRL, though in slightly
different view as
obtained with the decompiler on DownArrow.
Attention. ViewKey does only work if Keyman+ version 5.2004 is on your 49+.
