B   to sing one of the 7 Bard's tunes for a combat round. (Bards only.)
P    to attack a Party member. (See the COMBAT SYSTEM section of your manual
     for an explanation of why this option would be used.)
U    to Use a magic item or missile weapon.
C    to Cast a spell from the spell class and spell name lists that appear
     (when using mouse only). Or type one of the four-letter spellcodes that

OTHER ADVENTURING COMMANDS
The following commands are available throughout the game, whether you're
peacefully exploring the streets of the city or cautiously investigating
dungeons. Click the option you want or press:

C    to Cast a spell. Click on a spellcaster's name, then select from the
     spell class and spell name lists that appear (when using mouse only). You
     can also type a spellcaster's character number or just press the function  
     key corresponding to their character number and then type one of the
     four-letter spellcodes listed in the manual. (Magic Users only.)
P    to start an intra-Party fight at any time.
B    to sing one of the 7 Bard's tunes while travelling. You can type the
     Bard's character number, click on a Bard's name or just press the
     function key that corresponds to their character number. (Bards only.)
A    to Ascend up a portal, only when a levitation spell is in effect, only in
     dungeons.
D    to go down a portal. Works only in dungeons.
?   to learn the name of the street your party is on and the time of day.
R   to Release a special character from the party.

     other characters will move to accommodate the new order.
S    to Save your game from anywhere. You can exit to DOS by answering Yes
     when prompted. (Does not work during combat or timed death sequences.)
     Note: Contrary to what the clue book and manual say, it is not necessary
     to return to Tangramayne to Save your game in the IBM version of The
     Destiny Knight.
Q    to Quit your game. Note: Using the Quit command outside the Adventurer's
     Guild does not save your game status. You may want to use this command if
     you find yourself in an untenable position in a city or dungeon and you
     want to return to DOS and restart.
T    to pause the game. Press any key to resume. (Does not work during combat
     or timed death sequences.)
U    to Use an item. Some items don't work unless you activate them with this
     command, some must be equipped to be Used and some run out of power after
     only one Use.
V    to turn the sound on or off.
Spacebar You can speed up a message display by pressing the spacebar after the
     first part of the message. The next message or window display will
     promptly appear.
