I think in Visual Studio, i'm a little foggy, but conio useta be present in VS
as of 6.0..  so you can #include <conio.h> i think in more recent versions, i
haven't played with any .NET though.. but i remember being able to just include
<windows.h>  then just adding the following to my header to get access to teh
console input functions.

#ifdef __cplusplus
extern "C" {
#endif

char*_cgets (char*);
int_cprintf (const char*, ...);
int_cputs (const char*);
int_cscanf (char*, ...);

int_getch (void);
int_getche (void);
int_kbhit (void);
int_putch (int);
int_ungetch (int);


intgetch (void);
intgetche (void);
intkbhit (void);
intputch (int);
intungetch (int);


#ifdef __cplusplus
}
#endif

then just calling getch() would get a hotkey.
