As people are creatures of habit, it is desirable that not just the 
dialogs and menus are built up in a consistent manner, but also that 
the most important functions of a program can be operated consistenty 
from the keyboard.

Actually there are a number of command-key combinations (shortcuts) 
that are either standardized, or which have established themselves as 
quasi (accepted) standards; in detail:

Standardized according to decisions of the developers conference in 
August '89:

 Key combination            Function 
 [Control]-[C]              Copy 
 [Control]-[F]              Find 
 [Control]-[O]              Open 
 [Control]-[Q]              Quit program 
 [Control]-[V]              Paste 
 [Control]-[X]              Cut 
 [Shift]-Upward arrow       Go one page back 
 [Shift]-Downward arrow     Go one page forward 
 [Shift]-Leftward arrow     Cursor to start of line 
 [Shift]-Rightward arrow    Cursor to end of line 
 [Control]-Leftward arrow   Move back by one word 
 [Control]-Rightward arrow  Move forward by one word 
 [ClrHome]                  Go to the start of the document 
 [Shift]-[ClrHome]          Go to the end of the document 

Not standardized, but accepted as standard in practice:

 Key combination  Function 
 [Control]-[A]    Select all 
 [Control]-[G]    Find next 
 [Control]-[M]    Save as... 
 [Control]-[N]    New document 
 [Control]-[P]    Print 
 [Control]-[S]    Save 
 [Control]-[R]    Replace 
 [Control]-[U]    Close top window 
 [Control]-[W]    Cycle to next window 
 [Control]-[Y]    Cut current line 
 [Control]-[Z]    Start shell 

Important note: All '[Alternate]-[Control]' key combinations are 
reserved for the operating system. As examples one can name here:

 Key combination                        Function 
 [Alternate]-[Control]-[Tab]            Task change under MagiC 
 [Alternate]-[Control]-[Delete]         Start Shutdown sequence 
 [Alternate]-[Control]-[Esc]            Program manager under MagiC 
 [Alternate]-[Control]-[Space]          Iconify current window 
 [Shift]-[Alternate]-[Control]-[Space]  Iconify application 

Note that shortcuts must not be duplicated within a menu structure or 
a dialog, and some keyboard shortcuts can give rise to problems when 
the application is run with a keyboard of a different nationality to 
that used by the programmer. This is due to both the absence of some 
characters on a keyboard as well as to different keyboard layouts; the 
latter may affect [Alternate] combinations in particular.
