\ The following struct is designed to keep track of the down keys - up to
\ 6 per report, plus related information.  The code is not currently
\ doing anything with the modifier byte or the reserved byte, but
\ including those makes it very convenient because the key# information
\ coming back from the USB report fits directly into the struct format.
\ The #keys-down and #regl-keys-dn bytes are not filled in by the USB
\ boot report but instead are calculated sometime after receiving the
\ USB report.
\ Note: fields >kbd-in-byte7, >kbd-in-byte8, and >kbd-in-byte9 are used
\       to potentially hold the shift, cntrl and altgraph, which are
\       actually reported as status bits in the >kbd-in-modkeys byte.

\ Various keyboard flags;

-1      instance value  ctrlflag        \ True if the ctrl key is down
-1      instance value  altgflag        \ True if the alt graph key is down
-1      instance value  powerflag       \ True if the power key is down
-1      instance value  monflag         \ True if the monitor key is down
-1      instance value  stopflag        \ True if the stop (L1) key is down
\ Following indicate special flags for "previous" report;
-1      instance value  pr-shiftflag    \ True if the shift key is down
-1      instance value  pr-ctrlflag     \ True if the ctrl key is down
-1      instance value  pr-altgflag     \ True if the alt graph key is down
-1      instance value  pr-powerflag    \ True if the power key is down
-1      instance value  pr-monflag      \ True if the monitor key is down
-1      instance value  pr-stopflag     \ True if the stop (L1) key is down
 
0       instance value  key-repeat-time \ Time of next repeat
\ 0       instance value  key-click
nokey   instance value  curr-repeat-key
        \ curr-repeat-key will hold the converted keyvalue which represents
        \ the currently repeating key.
 

\ Following will be set if several special keys have been entered
\ but the control key was given the highest priority.  Without this
\ flag we end up applying the control offset if the control key is
\ down - even if shift (a higher priority key) is down.
