Today I've attended a Jumpstart session by Andy Pedisich at the ADMIN2007 Europe conference.

Along a lot of other really useful stuff, tricks and best practices, he showed us a Excel sheet, he developed years ago, which he uses to add databases (with the same file name and path, like log.nsf) from a lot of servers to his workspace. Essentially,

• he opens the servers view in his Domino Directory,
• selects the servers,
• copies the selection as table,
• opens the excel sheet,
• pastes the servers,
• edits the file name of the database,
• selects and copies the calculated @Command formulas to add the database to the workspace,
• creates a new Toolbar button,
• pastes the @Commands,
• closes the Toolbar button and
• clicks on it.
  
  Seeing this, I wondered, if there is no short cut? And really, there is:

Just create one new Toolbar button once (File - Preferences - Toolbar Preferences..., Customize, Choose a Toolbar to modify and in the Toolbar contents click New - Button..., ) with the following formula:

_names := @Subset(@MailDbName; 1) : "names.nsf";

_servers := @PickList(ustom _names; "Servers"; "Select servers"; "Select servers to add database from"; 3);

_db := @Prompt(kCancelEdit "Enter database"; "Enter the file name and path of the database to add."; "log.nsf");

@For(
n := 1;
n <= @Elements(_servers);
n := n + 1;
@Command(ddDatabase _servers: _db)
)

If there are more servers or address books to choose the Domino Directory from, you could replace the first line with:
_names := @Prompt(hooseDatabase "Choose Domino Directory"; "Choose the Domino Diretory to choose the servers from");

Or if there is only one Domino Directory and you have a current local replica, you could use something like the following line in place of the first line above:
_names := "" : "server-names.nsf";

Update:
The square brackets around AddDatabase (in the @Command) were missing. They were removed by the blog engine, because the text was formatted in blue?!?!?
Thanks to Andy Pedisich for notifying me.
