The Home-View tab in both Database mode and Sandbox mode gives access to five different groups: Clipboard, Game, Annotation, Infinite Analysis and Game Analysis
The Clipboard Group
Paste allows you to paste a game in PGN or a position in EPD format from the clipboard to the Notation window.
Copy as PGN copies the game from the Notation window to the clipboard in PGN format.
Copy as EPD copies the current position to the clipboard in EPD format.
Board Image creates a copy of the Board window in the clipboard
The clipboard options are better described in the Windows Clipboard section of the Basic Working Procedures.
The Game Group
Save saves the game to the current database. Note that this applies to the Sandbox as well as Database mode.
New. This button, which is only available in Database mode, creates a new game in the database.
Setup position allows you to set up a position. You can use that function when you want to start a new game from a non-standard position.
Reload. This button is only available in Database mode and allows you to reload a game from the database. If you have made some changes to a game and decide that you want to revert to the original game, you'd simply click the Reload button.
The Annotation Group
Annotate opens the Annotations editor window. The window will be opened up with the "Short after" tab active by default. You can also open the same window up in the Long after and styles tabs, using the commands in the drop-down menu.
Remove allows you to delete comments from the game.
The Annotation group options are explained in detail in the Commenting Games section of the Basic Working Procedures.
The Analysis Group
Analyze starts infinite analysis. When the Notation window is active, you can also start infinite analysis by hitting the space bar. Clicking the triangle at the bottom of the button will open a menu where you can select “Options” which displays the “Infinite analysis options”.
Start Custom starts infinite analysis with customized settings.
The Infinite Analysis section of the Basic Working Procedures has a detailed description of how to use infinite analysis.
The Game Analysis Group
