PUSH START - NEXTtext with the
PLAYER CHANGE ?text so that you know you're at the
PLAYER CHANGE ?screen rather than the

SPACE makes sense to use as a trigger button in games but there is no clear second choice, even though MSX games often uses M or N as a second trigger button when the player is using the keyboard, possibly popularized by Konami. On later computers (including modern IBM PCs) it's common to use Z and X (where Z is "A"/confirm/jump and X is "B"/cancel/attack) as trigger buttons for games that only need two buttons, but I don't think I've seen this in MSX games.
10 K$=INKEY$
20 PRINT ".";
30 IF K$=CHR$(24) THEN 50
40 GOTO 50
50 END
This program simply prints out dots until you press the seldomly used SELECT key (code 24), which is quite a unique key for the MSX keyboard. In openMSX the SELECT key is mapped to F7 by default. CTRL+X also works because that's the control code for the SELECT key.
