The Navigation Bar
With this bar under the chessboard you can perform some basic functions:
With the first four buttons on the left you can jump within the game, with the ''
Demo'' button start a game of the engine against itself, or the engines against
themselves, if you have 2 currently loaded. With the 2 rightmost buttons you can
switch to the analyse or edit mode.
1. Start of game button: Jumps to the start of the game, if clicked with the left
mouse button. If you click on the right mouse button, Arena jumps 5 moves
backward.
2. To left button: Jumps one move backward. If you right click on the button, a
dialog is shown where you can select th move number you want to jump to (same
function as Game/ Go to move of CTRL+G).
3. To right button: Jumps one move toward the end of the game. With a right click
the go to move dialog is shown, too.
4. End button: Jumps to the end of the game. If you click on the right mouse
button
, Arena jumps 5 moves forward.
4. "Chip" button: Tells the current engine to start calculating ("Move now"
function). If the engine is already calculating, the button displays a stop-sign.
You can also click on the chip- or stop-sign with the right mouse button
to stop the calculations of the engine.
6. Demo button: Starts the demo-mode. The engine will play against itself, or the
engines against themselves, if you loaded two of them. This is suitable for a
short
series of test games. For longer series the engine tournament is better. You find it
under Engines Tournament. Right-click on the button to get a small pop-up menu
to play a number of games in demo mode.
7. Analyse button: Starts up or ends the analysis mode with the engine(s). They
can
not execute moves on their own in this mode. You can jump forward and backward
in
the game with the navigation buttons or select the move right away in the game
list
without having to stop analysis mode. You can also select a different position in
the the EPD list without stopping analysis beforehand. Please note that the
engines
are heavily loaded and only react slowly to your commands. So don't click too
rapidly in succession on the navigation buttons. It is possible that this way the
engines get out of sync with Arena. If that should happen, the best to do is to
restart the engine(s).
8.Edit button: If this button is down, you can enter a game without interference of the engine(s).
This would be the case if the edit button is not pressed and you enter a move. They would
simply answer your move like in a normal game.
