$LK,"Echo",A="MN:Echo"$() turns on or off raw data going into the lexical analyzer.
$LK,"CTrace",A="MN:CTrace"$() unassembles code generated from the HolyC compiler.
$LK,"Trace",A="MN:Trace"$() unassembles code generated from the HolyC compiler.
$LK,"OTrace",A="MN:OTrace"$() shows intermediate code coming-out after optimization. $LK,"OTraceMask",A="MN:OTraceMask"$() ctrls which passes are displayed.
$LK,"PassTrace",A="MN:PassTrace"$() shows intermediate code coming-out after optimization. The bits ctrl which passes are displayed.

* There is a heap check utility which can find leaks. Use $LK,"HeapLog",A="MN:HeapLog"$(), and $LK,"HeapLogRep",A="MN:HeapLogRep"$(). It's a really simple program which intercepts $LK,"MAlloc",A="MN:MAlloc"$() and $LK,"Free",A="MN:Free"$(). You can customize the code to find other heap issues.
* You can define handler functions for $FG,2$<CTRL-ALT-letter>$FG$ keys with $LK,"CtrlAltLetCBSet",A="MN:CtrlAltLetCBSet"$(). They operate either in a interrupt environment or in the window mgr when it queues kbd msgs. You can do $LK,"Raw",A="MN:Raw"$() output. $FG,2$<CTRL-ALT-letter>$FG$ handlers take a scan_code as an arg.

* If you recompile $FG,2$Kernel$FG,2$$FG$ with $LK,"MakeOSDrvBootInstall",A="MN:MakeOSDrvBootInstall"$(), you can set the $FG,4$MemInit$FG$, option to initialize memory to a value at boot, the $FG,4$HeapInit$FG$ option to cause mem alloced off the heap to be initialized or $FG,4$VarInit$FG$ option so both global and local vars will be initialized to a value. Pick a non-zero value to discover uninitialized var bugs. You can set $LK,"sys_var_init_flag",A="MN:sys_var_init_flag"$, and $LK,"sys_heap_init_flag",A="MN:sys_heap_init_flag"$ directly after booting.
