### Game

New
  Start a new game.
Rated Game
  Start a new rated game against the computer.
Game Variant
  Select a game variant and start a new game of this game variant.
Game Info
  Display or edit additional information about the game like the name of the players or the date when the game was played.
Undo Move
  Undo the last move played and remove it from the game tree. Undoing a move is only possible if it is the last move in the current variation (i.e. a leaf node in the game tree; use Edit/Truncate to remove inner nodes of the game tree).
Find Move
  Find a legal move for the current color and display it for a few seconds on the board. Selecting this item repeatedly will show all legal moves.
Open
  Load a saved game. The board position after loading will be the last position in the main variation unless the game starts with a setup position. If the game starts with a setup, the board position will be the first position instead. This avoids that solutions are immediately shown if the file contains a Blokus puzzle as a setup with the solution as the main variation.
Open Recent
  Load a recently used game.
Save
  Save the current game.
Save As
  Save the current game under a new file name.
Export/Image
  Save the current position as an image file. Several image file formats are supported, the file format is derived from the file name ending (e.g. ".png" for the PNG format).
Export/ASCII Art
  Save the current position as a text diagram. The text diagram should be viewed using a monospace font.
Quit
  Quit Pentobi.

### Go

Beginning
  Go to the beginning of the game.
Backward
  Go one move backward in the current variation. The corresponding button in the toolbar supports autorepeat if pressed and held.
Forward
  Go one move forward in the current variation. If the current position has several follow-up variations (i.e. the current node in the game tree has several child nodes), the first variation will be used. The corresponding button in the toolbar supports autorepeat if pressed and held.
End
  Go to the end of the current variation. Like Forward, this also uses the first variation in positions with several follow-up variations.
Next Variation
  Go to the next variation to the last move played (i.e. the next sibling node of the current node in the game tree).
Previous Variation
  Go to the previous variation to the last move played (i.e. the previous sibling node of the current node in the game tree).
Go to Move
  Go to the move with a given move number in the current variation.
Back to Main Variation
  Go back to the last position in the current variation that belonged to the main variation.
Beginning of Branch
  Go back to the last position in the current variation that had an alternative move.
Find Next Comment
  Go to the next position that has a comment. If the comment text field was not visible, it will become visible. Selecting this item repeatedly will show all positions with comments in the game tree.

### Edit

Move Annotation
  Add a chess-style annotation symbol (e.g. !!) to the current move. The symbols are appended to the move numbers in the status bar and, depending on the configuration of Move Marking, on the board.
Make Main Variation
  Make the current variation the main variation of the game. This reorders the nodes in the game tree such that the current variation becomes the main variation.
Move Variation Up
  Changes the order of variations such that the current position will appear earlier when iterating over the variations with Next/Previous Variation.
Move Variation Down
  Changes the order of variations such that the current position will appear later when iterating over the variations with Next/Previous Variation.
Delete All Variations
  Delete all variations but the main variation. If the current position is not in the main variation, it will first be changed to a position as in Back to Main Variation.
Truncate
  Remove the node with the current position, including any subtree, from the game tree.
Truncate Children
  Remove all child nodes of the node with the current position from the game tree.
Keep Only Position
  Delete all moves and keep only the current position as a setup. This can be used to create files that start with a given fixed position.
Keep Only Subtree
  Like Keep Only Position but does not delete the moves after the current position.
Setup Mode
  Enter or leave setup mode. In setup mode, pieces can be placed anywhere on the board, even in violation of the game rules. Existing pieces can be removed from the board by clicking on them. The currently selected color also determines the color to play after the setup is finished. It can be changed with Next Color or by clicking on the orientation selector while no piece is selected. Setup mode can only be used if no moves have been played yet.
Next Color
  Choose the next color for selecting pieces. This can be used for example to enter game records, in which moves of a color were skipped because the color ran out of time.

### View

Toolbar
  Show or hide the toolbar.
Toolbar Text
  Configure the appearance of the toolbar.
Comment
  Show or hide a text field to display or edit comments on the current position.
Move Marking
  Change the way moves are marked on the board. The options are to mark the last move played with a dot or with a number, or to show the numbers of all moves, or not to show any marks.
Coordinates
  Display coordinates around the board for the fields on the board. The convention for the coordinates is the same as in the Blokus SGF file format used by Pentobi.
Show Variations
  Appends a letter to the move number on the board if the move has variations. If moves are marked with dots instead of numbers, a circle will be used instead of a dot for moves not in the main variation.
Fullscreen
  Make the main window full screen or leave full screen mode. It is platform-dependent if the window menu is shown in full screen mode. To leave full screen mode without using the window menu, press the F11 key.

### Computer

Computer Colors
  Select which colors are played by the computer.
Play
  Make the computer play a move for the current color. This can be used to change the color the computer plays or to resume playing after navigating in the game tree. If the computer did not already play the current color, it will play this color (and only this color) from now on.
Play Single Move
  Make the computer play a single move for the current color without changing the colors played by the computer.
Stop
  Abort the current move generation. You can make the computer continue to play by selecting Play.
Level
  Change the playing strength of the computer. Higher levels are stronger but can make the computer take a long time for playing moves on slow computers. The computer will remember the level last used separately for each game variant and restore it when the game variant is changed.

### Tools

Rating
  Show a dialog window with the rating of the user in the current game variant.
Analyze Game
