Tagging
Each card has an 'tagged' field which is shown by the checkbox in the upper left corner of the application window. Cards are tagged/untagged by pressing Ctrl+Space or clicking .
The Tag menu performs operations on tagged cards. For example, a list of all tagged cards can be viewed by pressing Ctrl+T, and the next tagged card can be activated by pressing Ctrl+G. Pressing Ctrl+M tags all cards matching the text in the "Find" control. Tagged cards can also be saved to, and subsequently merged from, a file.
To tag a card in the list view, press Space or Control+Space. The check box icon on the main window toolbar will be updated to reflect the new tag setting.

The keys Ctrl+0 through Ctrl+1 activate the card with the respective hotkey. Hotkeys are set by pressing Alt+#.
System-Wide Copy To New Card
Pressing Left Ctrl + Left Windows + Numpad * pastes the clipboard to a new card, regardless of what application is active.
